Mandatory vs 'Opt-in' DAP applications

Opt-in DAP application

Where the estimated development value is $2 million or more, applicants can elect to have a Development Assessment Panel (DAP) determine their application instead of the local government.

Mandatory DAP application

Where the estimated development value is $10 million or more, determination by a DAP is mandatory.

The DAP process

The development application process follows the same process as a normal planning application determined by the Shire, except that the decision maker is the Joint Development Assessment Panel (JDAP).

  1. The Shire must prepare a technical report (referred to as a Responsible Authority Report), based on the objectives and requirements of the Shire’s Local Planning Scheme No. 4 (LPS4) and other relevant considerations within the planning framework such as State Planning Policies, the Local Planning Strategy etc.
  2. After considering the Responsible Authority Report (RAR) a decision will be made by the JDAP.
