A large shark managed to get into a swimming enclosure near a popular picnic spot on Macleay Island, off the southeast Queensland coast.
Police were alerted to the bull shark in the swimming area, which is surrounded by a net, at Macleay Island in Moreton Bay about 7.30am (AEST) on Saturday.
The shark stayed in the enclosure near the picnic spot Pats Park for some time before swimming out about 11am (AEST), according to police on the island.
‘‘The shark net there isn’t real flash. It doesn’t quite go down to the sea bed so anything can slide in underneath,’’ Sergeant Dave McDougall said.
He said it was the first time he heard of a shark swimming into the section.
