Serpentine Reserve BMX track temporarily closed

Published on 23 December 2025

Serpentine Reserve BMX track is temporarily closed after building materials removed from the site yesterday, and tested today, were today found to contain asbestos.

The City of Onkaparinga responded immediately to organise its collection yesterday by the council’s licenced asbestos assessor and removalist, after a quick-thinking resident notified the council of building material fragments found near the BMX track.

It’s unknown how the material came to be at the site, though it’s thought to potentially be long-ago illegally dumped material that was unearthed by contractors ahead of works to improve the bike jumps.

Council and community works to shape, improve and maintain the site’s dirt bike jumps – through the council’s Community Dig Days initiative – took place on Tuesday 16 December, but the materials weren’t identified at that time.

Soil for the dig day was tested before being delivered to the site, and the test results advised the material was suitable for use.

The council has temporarily closed the BMX track with bunting today, and is installing signage out of an abundance of caution. Temporary fencing to be installed onsite on Wednesday 24 December.

The EPA is aware of the situation, and the council will share more information as the remediation works progress. The council is also reaching out to participants involved in the 16 December dig day.
