Dirt jumps project update

We are working with local riders to improve and maintain dirt jump tracks and sought your input! This pilot project was chance to help design and build the jumps you ride!

We are currently progressing works at our dirt jump locations in O’Halloran Hill and Seaford.

Below is a summary of the status for each site. Please visit the individual project pages for detailed information and updates.

Serpentine Reserve, O’Halloran Hill

The Serpentine BMX track is currently closed following the discovery of asbestos-containing material at the site.

The track was initially closed on 23 December 2025 after small pieces of building material found on the surface were tested and confirmed to contain asbestos.

We have engaged a specialist contractor to undertake remediation works. This work is scheduled to commence in early April 2026 as follows:

• Site remediation

Initial works will involve removal of asbestos, certification and removal of soil. This work will involve statutory notification to SafeWork SA, establishment of an exclusion zone, airborne fibre monitoring and relevant certification

• Importation of clean fill

Following remediation works, new certified clean soil will be imported to the site.

• Reconstruction of BMX track

The BMX dirt jumps will be rebuilt at the same location in the same design using the new clean soil.

We appreciate your patience and understanding while these important works are undertaken. We anticipate the BMX track being reopened in mid-2026.

The Quarry, Seaford

Community feedback has been incorporated into a final concept plan for the altered dirt jumps at The Quarry.

In response to recent challenges experienced at Serpentine Reserve, works at Seaford Quarry will be completed entirely by an appointed contractor to ensure all safety and compliance requirements are met.

Works are currently anticipated to commence in early April 2026, subject to site and contractor scheduling.

Background

This pilot program is all about fixing and maintaining the jumps that are already here. It’s NOT a full rebuild or upgrade. So:

• No new jumps will be added, but we might reshape or adjust the current ones to make them safer and better to ride.
• There will not be any new extras like benches, lights, or toilets.
• No trees will be removed.
• All changes will stay within the current dirt jump area – no big changes or extensions.
