Beaches from Nelson Bay marina to Fly Point will remain closed on Tuesday after a sewage leak, Port Stephens Council has confirmed.
The council is currently waiting on water quality test results to determine when it will be safe to reopen the beaches. The community is advised to avoid swimming in the area.
