The Wynnum wading pool will not be open during the Australia Day long weekend.
Councillor Peter Cumming for the Wynnum Manly Ward made the announcement on Facebook last night.
The council has been forced to drain the pool and do a thorough search after an unidentified person was pricked by a needle yesterday.
It is expected to reopen next week once the sand has been cleaned.
This weekend is set to be a busy period on the Wynnum Manly foreshore, with families flocking to the area due to the warm weather and ample playground and BBQ areas available.
