Are you aiming to achieve Green Star certification for your project?
Are you wanting to plan ahead for this year?

We understand that many project teams have timelines set around major events. To support this, we've created the guidelines below (based on typical time frames), which specify the deadlines you'll need to meet to have your project certified in time for key milestones.

Please note that processing times at the end of year, and end of financial year, are extended due to peaks in submissions during these periods. Please be advised these dates are indicative only.
