Applications for Round Two are now open.
Project proposals must be submitted to Lead Agencies between 9am (local time) Monday 22 January to 5pm (local time) Wednesday 20 March 2024. 
Applicants must contact the Lead Agency in their jurisdiction to discuss proposals and check the Lead Agency’s website for information on their DRF application process.
Lead Agencies will coordinate and consider proposals and have until 5pm AEST Friday 29 April to submit applications on behalf of their jurisdiction to NEMA.
Subject to the number of applications received, successful projects are expected to be announced in the second half of 2024.
