Warning signage, security, and barricades have been established to protect the public from exposed areas and potential health risks.

The public is advised to wash hands thoroughly if in contact with wastewater and to seek medical attention if experiencing symptoms like headaches or nausea.

The overflow has contaminated several areas, including Bruce Lee Reserve and nearby locations such as Hamilton Road and Watsonia Park in Spearwood.

In response to the spill, Water Corporation has advised against fishing and crabbing in the Swan River at specific locations, particularly near the Fremantle Sailing Club.

Images shared online depict streets in Spearwood covered in inches of wastewater, highlighting the severity of the situation.

Water Corporation has halted flows and is currently working on repairs, which are expected to take time due to the complexity of the wastewater network.

A significant sewage spill into Perth's Swan River has been traced back to a burst sewer main on Hamilton Road in Spearwood, which occurred on June 6, 2025.

As of June 9, 2025, pools of human waste remain on soccer pitches in Beaconsfield and have flowed into the Fremantle commercial and recreational fishing boat harbor.

Repairing the burst sewer main is complex and requires prefabrication of a new pipeline section instead of simple welding.

Water Corporation is collaborating with various governmental departments to ensure public safety during this incident.

Warnings have been posted near stagnant sewage pools, urging the public to avoid jet skiing, sailing, drinking, or swimming in the contaminated water.

Residents in the affected areas have reported strong sewage odors, with some likening the smell to that of a toilet.
