What Is a Development Application (DA)?
A Development Application is a formal request to a local council (or state planning authority) for permission to carry out development — including subdivision, construction, demolition, or change of use. The DA process ensures that proposed developments comply with planning laws and are assessed for their impact on the community and environment.
The DA Process: Step by Step
Step 1: Pre-Lodgement Meeting (Recommended)
Before lodging a DA, most councils offer a pre-lodgement meeting with a planning officer. This is strongly recommended because it identifies potential issues before you spend money on detailed plans and can significantly reduce assessment time.
Step 2: Prepare the DA Package
Mandatory documents:
- Completed DA application form
- Site plan (showing existing and proposed lot boundaries)
- Statement of Environmental Effects (SEE) or Planning Report
- Survey plan (existing lot dimensions, easements, services)
- Title search and ownership documents
- Application fee payment
Technical reports (as required):
- Stormwater management plan
- Traffic impact assessment
- Bushfire assessment
- Flood impact assessment
- Ecological assessment
Step 3: Lodgement
DAs are lodged through the state planning portal (NSW Planning Portal, PlanSA, VicSmart, etc.) or in person at council offices.
Step 4: Notification and Referrals
Most DAs are publicly notified for 14–28 days, allowing neighbours to make submissions. The DA may also be referred to external agencies.
Step 5: Assessment and Decision
The planning officer assesses the DA against the relevant planning scheme. Possible outcomes: Approved, Approved with modifications, or Refused.
DA Assessment Timeframes by State
| State | Statutory Timeframe | Typical Reality | |-------|--------------------|-----------------| | NSW | 40 business days | 3–6 months | | QLD | 20–30 business days | 3–5 months | | VIC | 60 days | 3–6 months | | WA | 60 days | 2–4 months | | SA | 40 business days | 2–4 months | | TAS | 42 days | 2–3 months | | ACT | 30 business days | 2–4 months |
Common Reasons DAs Are Refused
- Non-compliance with minimum lot size — proposed lots don't meet zone requirements
- Insufficient road frontage — lots don't have adequate street access
- Flood or hazard constraint — development not permitted in high-risk areas
- Inadequate stormwater management — proposed drainage doesn't meet standards
- Vegetation clearing — protected vegetation cannot be cleared
Reducing DA Risk: The Role of Feasibility Assessment
The most effective way to reduce DA risk is to conduct a thorough subdivision feasibility assessment before purchasing a site or lodging a DA. A professional assessment will identify planning constraints before you commit capital, confirm compliance with zone requirements, and flag overlay constraints that could prevent approval.
