Case Studies
Evidence from comparable waste and resource-management facilities — with clear notes on what applies to DPA-14 and what does not.
Start with the Auditor-General report
The most directly relevant case study is the ACT Auditor-General's Phillip pool report. It is not about green waste, but it is about the same type of issue: whether a Territory Plan change was supported by clear, specific and accurately presented evidence.
Read the Auditor-General lessons first, then compare the Swanbank odour case study.
Read the Auditor-General lessonsHow to read these case studies
No case study is identical to DPA-14. Each involves different site conditions, regulatory frameworks, facility scales, and community contexts. The value of case studies is not to assert that DPA-14 will produce the same outcomes — but to identify what questions have proved important at comparable facilities and to inform what residents should ask about DPA-14.
Case 1: ACT Auditor-General — Phillip pool Territory Plan report
Why it matters: this is the closest governance comparison because it concerns an ACT Territory Plan change. The lesson for DPA-14 is that public documents should accurately explain what evidence was relied on, what analysis was not done, and why the planning change is justified.

Case 2: Swanbank, Queensland
Important differences from DPA-14
Swanbank, Queensland is not directly comparable to DPA-14. Swanbank involved a landfill, power generation infrastructure, and a range of industrial odour sources well beyond green waste composting. The scale, regulatory environment (Queensland, not the ACT), and cumulative source mix are different from what is proposed at Block 1653 Belconnen. These differences must be kept clearly in mind when reading the lessons below.
Background
Swanbank and New Chum are industrial areas in the Ipswich region of South-East Queensland. Queensland Health established a Public Health Inquiry after community concerns about odour from those industrial areas.
The inquiry examined the health effects of odour and recommended actions to lessen impacts. Queensland Health states that the final report found the odours were not a cancer risk, but were highly offensive and potentially harmful to health and wellbeing.
Primary sources
Queensland Health established the Swanbank Public Health Inquiry to investigate health effects of odour from the Swanbank and New Chum industrial areas and recommend actions to lessen impacts. The final report was released on 19 November 2025.
Lesson 1: Odour monitoring and enforcement
Queensland Health states that existing legislative frameworks and instruments may not support effective assessment, management and enforcement to lessen odour. The lesson for DPA-14 is that odour controls should not rely only on broad assurances or operator-level compliance statements. Residents should be able to see what monitoring will occur, who will conduct it, how results will be reported, and what enforcement action will follow if odour conditions are breached.
Question for DPA-14: What odour monitoring conditions would apply to operations at Block 1653 Belconnen, how would results be made publicly available, and what enforcement action would follow if conditions are breached?
Lesson 2: Health impact assessment
Queensland Health states that the Swanbank odours were highly offensive and potentially harmful to health and wellbeing. It also identifies reported symptoms including respiratory, ear-nose-throat, neurological, gastrointestinal, skin and mental-health symptoms. The report also states that odorous chemicals do not need to be at toxic levels to affect health.
The lesson for DPA-14 is that health and wellbeing concerns should be assessed before operations begin, not only after complaints are made.
Question for DPA-14: Has a site-specific odour, air quality and health assessment been prepared for Block 1653 Belconnen, and has it been publicly released?
Lesson 3: Cumulative impacts from multiple waste and industrial sources
Queensland Health states that there were other potential sources of offensive odour in the Swanbank and New Chum industrial areas. That matters because cumulative impacts can be harder to assess than impacts from a single facility.
The lesson for DPA-14 is that government should not assess each possible use in isolation if the planning change could support co-location or staged intensification over time.
Question for DPA-14: Has the potential for co-location of additional waste or resource-management uses on or near Block 1653 been addressed in the evidence base? See also the Evidence Gaps page.
Lesson 4: Complaint response and regulatory accountability
Queensland Health states that government response actions included stricter licence conditions, interim measures to lessen odour impacts, and an inter-departmental steering committee supported by community and industry reference groups.
The lesson for DPA-14 is that complaint handling should be clear before operations begin. Residents should know who receives complaints, how quickly complaints must be investigated, what information will be made public, and what enforcement powers are available.
Question for DPA-14: What complaint mechanism would apply to Block 1653 operations, what are the required response timeframes, and which ACT regulator would be responsible for enforcement?
What Swanbank suggests for DPA-14
Swanbank is not a direct comparison with Block 1653 Belconnen. It involved a larger industrial area, multiple operators, landfill, composting, recycling/resource recovery and other odour-producing activities. However, it is relevant because it shows that odour and related exposure questions can extend beyond a simple site boundary or assumed short buffer distance.
The Swanbank inquiry considered surrounding suburbs and distance zones extending well beyond 1 kilometre from the industrial area. It also reviewed evidence that compost-associated bioaerosol indicators can travel beyond composting facility boundaries, with some indicators returning to near-background levels only after distances measured in kilometres, depending on site, season, operating conditions and the indicator measured.
The lesson for DPA-14 is not that the same impacts will occur at Block 1653. The lesson is that the ACT Government should clearly explain the evidence basis for any odour, bioaerosol, air-quality and health assessment area used for Block 1653, including why that area is sufficient for nearby and future West Belconnen / Ginninderry communities.
Question for DPA-14: See the Evidence Gaps page for what a defensible odour and bioaerosol assessment area should show.
Other relevant experience
The following areas of comparable experience may also be relevant to DPA-14.
- Other ACT composting operations: Where comparable composting operations have previously been approved in the ACT, their operational conditions and compliance history are relevant evidence.
- Interstate composting facility investigations: Other Australian jurisdictions have conducted reviews of composting facility odour complaints and regulatory responses. These may offer additional lessons about monitoring, setback distances, and community engagement.
