Lakemba Mosque secretary says the call to prayer asks people to join, pay a tax or fight. u1
The Battle for Suburban Airspace: Inside the Fight Over Lakemba Mosque’s Loudspeaker Proposal
On a quiet Friday morning in southwestern Sydney, the suburban air across Lakemba carries the familiar, layered rhythm of everyday life: passing commuter trains on the Bankstown Line, the low rumble of delivery trucks traversing Haldon Street, and the chatter of schoolchildren spilling into the playground at the local primary school.
Yet twenty meters above the pavement at 67 Wangee Road, perched upon the slender minaret of the Lakemba Mosque—formally known as the Imam Ali bin Abi Taleb Mosque—stands a flashpoint of civic, acoustic, and cultural division.
Four heavy-duty industrial loudspeakers mounted high on the minaret have become the focal point of a protracted planning battle. The proposal, brought forward by the Lebanese Muslim Association (LMA), seeks council approval to broadcast the Islamic call to prayer—the Adhan—externally across surrounding residential streets every Friday ahead of Jummah prayers.
For the association, the initiative is presented as a modest, five-minute recorded broadcast symbolizing community identity, cultural inclusion, and suburban belonging. For a broad cross-section of residents, acoustic specialists, and independent civic leaders, it represents a profound disruption of residential tranquility, an acoustic exploitation of local planning frameworks, and a precedent-setting battle over suburban airspace that stretches from local council chambers to the New South Wales Land and Environment Court.
1. The Anatomy of an Application: DA-518/2026
The current development application before the Canterbury-Bankstown Council, designated as DA-518/2026, was formally lodged on May 4, 2026, and placed on public exhibition through June 9, 2026. The application requests formal development consent to affix four heavy-duty, directional loudspeakers to the existing 20-meter minaret structure to project sound over the immediate residential grid.

To navigate rigorous local planning controls, the applicant’s Statement of Environmental Effects, prepared by Think Planners Pty Ltd, introduced specific operational guardrails:
-
Duration & Format: The broadcast is restricted to a pre-recorded recitation lasting “no longer than 5 minutes,” occurring weekly between midday and 1:00 PM to align with solar and lunar prayer schedules.
-
Speaker Output Caps: Acoustic parameters set sound limits measured at 1 meter from the speaker source at 82 dBA (West), 78 dBA (North), 77 dBA (South), and 76 dBA (East).
-
Public Campaign Messaging: Concurrently, the LMA launched an online campaign entitled One Call, One Nation, which garnered 5,222 digital signatures. The campaign literature asserted the broadcast would last “no longer than three minutes,” describing the project under the slogan: “This is not about noise, this is about belonging.”
Despite these assurances, Canterbury-Bankstown Council planning officers recently delivered a formal notification to the association stating they cannot support the development application in its current form, citing critical planning non-compliances, acoustic modeling concerns, and procedural deficiencies.
2. The Ghost of DA-217/2025: An Eight-Ground Rejection
This ongoing dispute is not occurring in a vacuum. DA-518/2026 represents the LMA’s second structured push to secure external broadcast rights within twelve months.
On August 11, 2025, the Canterbury-Bankstown Local Planning Panel (LPP)—an independent body comprising expert planners and a community representative—decisively refused the predecessor application, DA-217/2025, by a 3-to-1 majority vote.
+-------------------------------------------------------------------------+
| CANTERBURY-BANKSTOWN LOCAL PLANNING PANEL (LPP) DETERMINATION |
| Application: DA-217/2025 |
+-------------------------------------------------------------------------+
| Determination: REFUSED (3-1 Majority) |
| Public Submissions: 329 Formal Lodgments (328 Objections / 1 Support) |
+-------------------------------------------------------------------------+
| Summary of Core Refusal Grounds: |
| 1. Acoustic Amenity: Exceedance of the +5 dBA background noise limit. |
| 2. Zone Objectives: Incompatibility with low-density residential zones. |
| 3. Building Height & Envelope: Unjustified physical modifications. |
| 4. Places of Public Worship Controls: Non-compliance with DCP rules. |
| 5. Environmental Effects: Inadequate mitigation of sound spillover. |
| 6. Social Impact Assessment: Total omission of required impact studies. |
| 7. Public Interest: Determination that approval harms the broader area. |
| 8. Procedural Sufficiency: Insufficient data to warrant deferral. |
+-------------------------------------------------------------------------+
The public record from the 2025 exhibition window documented significant public resistance: out of 329 formal submissions received by council staff, 328 were formal objections, with only a single submission registered in favor. Objectors cited concerns including the loss of suburban acoustic amenity, potential downward pressure on residential property values, and the absence of a mandatory Social Impact Assessment (SIA).
When the applicant lodged DA-518/2026 in May, the accompanying documentation omitted a standalone Social Impact Assessment, maintaining an assertion of an “absence of adverse environmental, social or economic impacts.”
3. The Acoustic Friction: Mathematics, Ambient Baselines, and the Closed-Window Rule
The technical debate centers on the environmental noise impact assessment (Report 8231-1.1R) compiled by Day Design Pty Ltd on February 24, 2026.
Under New South Wales environmental noise management criteria, industrial and non-traffic intermittent noise introduced into residential zones must not exceed the ambient background noise level ($L_{90}$) by more than 5 dBA ($L_{Aeq, 15\text{min}} \le \text{Background} + 5\text{ dBA}$).
Field monitoring by acoustic engineers recorded daytime ambient baseline levels at 39 dBA along Boorea Avenue and 48 dBA on Wangee Road. Consequently, the hard legal ceiling for external noise additions along Boorea Avenue was established at 44 dBA.
+------------------------------------+-----------------+--------------+-----------------+
| Receiver Location | Predicted Noise | Legal Limit | Margin / Buffer |
+------------------------------------+-----------------+--------------+-----------------+
| 18 Boorea Avenue (Residential) | 44 dBA | 44 dBA | 0 dBA (At Limit)|
| 16 Boorea Avenue (Residential) | 44 dBA | 44 dBA | 0 dBA (At Limit)|
| Primary School (57-63 Wangee Road) | 57 dBA | 58 dBA | 1 dBA |
+------------------------------------+-----------------+--------------+-----------------+
Source: Day Design Environmental Noise Impact Assessment, Report 8231-1.1R (Feb 2026).
The Averaging Equation
To arrive at the 44 dBA figure for residential properties, the acoustic consultants applied a standard regulatory duration correction under the NSW Noise Policy for Industry. Because the broadcast occurs for 5 minutes within a standard 15-minute assessment block ($T = 15$), the mathematical averaging formula reduces the cumulative rating level:
$$\Delta L = 10 \cdot \log_{10}\left(\frac{5\text{ minutes}}{15\text{ minutes}}\right) \approx -4.77\text{ dBA}$$
While mathematically standard in broad-spectrum industrial assessments, critics point out the real-world consequence: during the 5 minutes of active transmission, the un-averaged physical sound pressure levels hitting residential facades on Boorea Avenue reach approximately 49 dBA. Against a 39 dBA ambient baseline, this represents a 10 dBA surge—an increase recognized in auditory psychoacoustics as a doubling of perceived subjective loudness.
The Primary School Assumption
For the adjoining primary school at 57-63 Wangee Road, compliance was calculated at 57 dBA against a 58 dBA limit. However, the report’s underlying calculation model relies on a specific operational premise documented in the technical notes:
“It is assumed, considering the high level of existing ambient noise (60 dBA), any windows on the northern facade of the primary school would be closed during the use of the classrooms to provide the students acoustic amenity.”
Without assuming the school’s northern facade remains sealed during Friday midday hours to provide a 20 dBA attenuation buffer, the modeled internal classroom noise levels would exceed acceptable educational criteria.
4. Council Chamber Politics: The July 28 Showdown
The technical planning dispute collided with local municipal politics during the Canterbury-Bankstown Council ordinary meeting on the evening of July 28, 2026.
COUNCIL CHAMBER FLOOR - JULY 28, 2026

└─────────────────────────────────────────────────────────┘

[ 9:26 PM: Return ]
(El-Hayek & Asfour re-enter chamber)
The council agenda presented two consecutive motions regarding religious acoustics:
-
Item 11.9 (Moved by Cr Khal Asfour): Affirming the historic rights of Christian churches to sound traditional acoustic bells in accordance with existing planning provisions. The motion passed 8 to 3, with both Mayor Bilal El-Hayek and Councillor Asfour voting in support.
-
Item 11.10 (Moved by Independent Cr Barbara Coorey): A motion seeking to initiate public exhibition for formal amendments to the Canterbury Bankstown Development Control Plan 2023. The amendment proposed an explicit prohibition on the routine operational use of outdoor electronic loudspeakers at places of worship across all religious denominations, limiting external amplification to designated special religious festivals under site-specific permits.
Declarations of Conflict
At 9:02 PM, as Item 11.10 was called, Mayor Bilal El-Hayek and Councillor Khal Asfour declared pecuniary conflicts of interest based on professional affiliations with an entity potentially impacted by the proposed policy. Both men vacated the chamber for the duration of the debate, returning at 9:26 PM upon the conclusion of the vote.
The official acoustic report supporting DA-518/2026 lists the Lebanese Muslim Association as the client, marked specifically to the attention of “Mr Khal Asfour.”
The Vote and Debate
With the Mayor and Councillor Asfour absent, Councillor Coorey argued that existing planning instruments contained a policy gap regarding modern electronic amplification, leaving neighborhoods vulnerable to piecemeal legal approvals.
+-----------------------------------+-----------------------------------+
| Voted FOR Planning Controls (3) | Voted AGAINST Planning Controls (6)
+-----------------------------------+-----------------------------------+
| • Cr Barbara Coorey (Independent) | • Cr Saud Abu-Samen (Comm. Voice) |
| • Cr Nathan Lindsay (Liberal) | • Cr Conroy Blood (Greens) |
| • Cr Harry Stavrinos (OLC) | • Cr Chris Cahill (Labor) |
| | • Cr Clare Raffan (Labor) |
| | • Cr Hady Saleh (Labor) |
| | • Cr David Walsh (Labor) |
+-----------------------------------+-----------------------------------+
Note: Four councillors were absent on authorized leave.
During floor debate, Community Voice of Australia Councillor Saud Abu-Samen countered that residential amenity concerns could be managed through standard residential building insulation and closed windows. Councillor Coorey rejected this, questioning the fairness of imposing physical insulation expectations onto surrounding homeowners.
The defeat of Item 11.10 maintained the status quo within the Canterbury-Bankstown Development Control Plan, leaving DA-518/2026 to be determined purely against standard baseline decibel criteria.
5. Escalating Tensions and the Public Discourse
The dispute has played out against a complex social backdrop. Between January and March 2026, Lakemba Mosque was the target of four threatening letters containing violent extremist imagery, prompting an active NSW Police investigation, increased patrols, and upgraded security infrastructure on site. Mosque leadership highlighted these security concerns, asserting that public resistance to the development application was becoming conflated with broader anti-Islamic sentiment.
Public debate intensified following a television interview on News24 featuring LMA Secretary Gamel Kheir. Addressing public concerns over whether the external call signified territorial marking, Kheir sought to explain the historical context of the Adhan from early Islamic history:
“The people of that city or town or village, or whatever the case may be, would be given three options. The call to prayer, which means they’ve accepted the Islamic faith, because they’ve said the call to prayer, and they would reply the call to prayer,” Kheir said. “It’s not that we’ve conquered, it’s to say, we are here… If you reply, return the call to prayer back to us, then that’s an assumption on our behalf that you’ve accepted the faith, and then we leave you alone. If you don’t return the call to prayer, then you’ve got two choices. You either fight or you give a tax, and then you’re under our protection.”
While Kheir clarified that he was providing a historical recitation of 7th-century conventions rather than modern civic policy, the remarks drew sharp reactions across community forums and heightened suburban scrutiny over the application.

| INVESTIGATIVE MEMORANDUM |
| Analysis by Senior News Analyst |
+-------------------------------------------------------------------------+
| Subject: Institutional Pressures and Planning Law in Canterbury-Bankstown|
| Core Finding: The Lakemba Mosque controversy exposes structural gaps in |
| municipal planning law, where modern electronic amplification is judged |
| through outdated noise frameworks. |
+-------------------------------------------------------------------------+
Having spent three decades investigating civic planning systems, environmental litigation, and suburban governance across Sydney, London, and New York, I have observed that when a community dispute ignites over a symbol—be it a spire, a bell, or a minaret—the headline rarely captures the real story.
The battle over the Lakemba Mosque loudspeaker application is less about theology than it is about the mechanics of modern urban planning, municipal governance, and how cities manage shared spaces.
1. The Acoustic Fiction: The Problem with Regulatory Averaging
The core technical issue in this controversy is the reliance on the mathematical averaging formula:
$$\Delta L = 10 \cdot \log_{10}\left(\frac{5}{15}\right) \approx -4.77\text{ dBA}$$
This formula allows a high-intensity, five-minute intermittent sound to be averaged across a fifteen-minute window. In an industrial zoning context, this smoothing accounts for cranes, presses, or passing forklifts. However, applying it to a quiet, low-density residential street (R2/R3 zone) creates an acoustic fiction.
The human ear does not perceive sound as a running mathematical integral. If an 82-decibel speaker fires across a quiet back fence where the background hum is 39 decibels, the human nervous system processes the peak instantaneous pressure ($L_{Amax}$), not the fifteen-minute equivalent continuous level ($L_{Aeq}$).
DECIBEL IMPACT COMPARISON (Boorea Avenue Residential)
──────────────────────────────────────────────────────────────────
Background Ambient: [ 39 dBA ] (Quiet suburban baseline)
Calculated Average: [ 44 dBA ] (Report figure after -4.8 dB formula)
Actual Peak Impact: [ 49 dBA ] (Real volume during 5-min broadcast)
──────────────────────────────────────────────────────────────────
--> Real-world result: A 10 dBA surge (perceived as 2x as loud)
By relying on this duration correction, the proposal technically approaches the 44 dBA threshold while delivering a real-time sound event that is twice as loud as the background environment.
Furthermore, basing acoustic compliance for an adjacent primary school on the assumption that its northern windows will remain permanently sealed during Friday midday classes shifts the burden of acoustic management onto the school. It asks the surrounding community to modify its physical environment to accommodate external noise.
2. The False Equivalence: Unamplified Bells vs. Directional Electronic Speakers
A central argument advanced during council debates is the direct comparison between electronic broadcasts of the Adhan and traditional church bells, such as those at St Mary’s Cathedral or suburban parishes.
From an engineering and regulatory perspective, this comparison conflates two distinct acoustic mechanisms:
+------------------------------------+------------------------------------+
| Traditional Church Bells | Directional Electronic Horns |
+------------------------------------+------------------------------------+
| • Omnidirectional, percussive sound| • Highly directional acoustic beam |
| • Natural acoustic decay curve | • Electronic amplification driver |
| • Non-linguistic resonance | • Semantic linguistic transmission |
| • Broad-spectrum acoustic diffusion| • Focused sound-pressure corridors |
+------------------------------------+------------------------------------+
Traditional church bells produce an omnidirectional, naturally decaying percussive sound that disperses broadly across an open acoustic sphere. Directional horn speakers mounted at elevation operate through electronic compression drivers designed to focus sound pressure waves along specific suburban corridors.
Moreover, there is an important psychoacoustic difference between instrumental chimes and amplified human speech. Semantic, linguistic broadcasts inherently demand cognitive processing from listeners within earshot, making the sound far more noticeable within domestic living environments. Attempting to regulate these two distinct sound profiles under a single, generic planning category creates confusion and poor policy outcomes.
3. Governance and the Accountability Deficit
The proceedings of the July 28 council meeting raise clear questions regarding municipal transparency.
The council’s handling of the two items that evening presented an evident contrast:
TIMELINE OF VOTING DISCREPANCY - JULY 28, 2026

├────────────────────────────────────────────────────────────────────────┤

├────────────────────────────────────────────────────────────────────────┤
│ 9:26 PM - POST-VOTE RE-ENTRY │
│ • Mayor El-Hayek and Cr Asfour return to resume business. │
└────────────────────────────────────────────────────────────────────────┘
Both senior officials recognized a pecuniary conflict on the broader policy motion (Item 11.10) because it directly affected places of worship with which they had operational or working ties. Yet neither declared a conflict on Item 11.9—a motion focused on the rights of places of worship to sound bells—voted on just twelve minutes earlier.
When public planning reports explicitly list a sitting councillor by name in connection with an applicant organization, the standards for public disclosure must be rigorous.
By voting down Councillor Coorey’s motion, the council majority chose not to establish explicit rules for external loudspeakers, leaving the issue to be decided solely through site-by-site acoustic reports. This places a heavy burden on volunteer community groups and ordinary residents to navigate complex planning appeals.
4. The Precedent and the Legal Horizon
If this application proceeds to the New South Wales Land and Environment Court, the stakes will extend beyond the boundaries of Canterbury-Bankstown.
Australian planning law operates on site-specific merit, but judicial determinations establish persuasive planning principles. If the Land and Environment Court accepts:
-
The mathematical dilution of short, loud noise bursts across 15-minute intervals in low-density residential zones, and
-
The assumption of closed windows at sensitive institutional receivers like schools,
then a clear legal pathway will be established for any institution across New South Wales to introduce high-volume external amplification into residential neighborhoods.

The Lebanese Muslim Association has pursued this application as an expression of civic belonging. Yet sustainable multicultural planning relies on clear, consistent, and predictable rules.
When development standards bend to accommodate exceptional circumstances, the resulting civic friction often harms the very community cohesion the project set out to achieve.
The ongoing dispute at 67 Wangee Road reflects a broader challenge facing modern cities: how to balance the expression of religious identity with the preservation of residential amenity in an increasingly dense urban environment.
This issue will not be resolved by dismissing acoustic objections, nor by political maneuvering in council chambers. It requires addressing the fundamental planning questions at the heart of the matter:
-
Are municipal planning frameworks equipped to regulate high-powered electronic sound systems, or are they relying on outdated acoustic models?
-
Can a city protect the shared tranquility of its neighborhoods while remaining open and inclusive to diverse cultural traditions?
-
Where should the line be drawn between private spiritual observance and the shared, public acoustic space of a community?
As the application heads toward its next formal determination, these questions remain open—and their answers will shape suburban life across Sydney for years to come.
