A man has drowned after disappearing beneath the surface of the water while swimming in an abandoned quarry near Perth on Sunday.
According to a police spokesperson, the young man jumped into the Red Hill Quarry pool of water and then surfaced to call out that he had injured his leg.
The man then disappeared under the water and was not seen again, prompting witnesses to call emergency services.
The RAC rescue helicopter flew to the site in Gidgegannup just after 4.10pm to help search for the man, who is believed to be in his mid-20s.
A WA police spokesperson confirmed to Daily Mail Australia that police divers began a search of the quarry, which contains water up to 25m deep, on Sunday night.
The man's body was found in the quarry at 2.30am on Monday morning and he was conveyed to St. John of God Hospital in Midland. Police will prepare a report for the Coroner.
The quarry stands on private property, and is not open to the public despite hundreds of trespassers visiting the site every year.
Authorities have previously warned of the dangers posed by the abandoned Red Hill quarry and warned trespassers not to enter, The West reported.
Road Safety Commissioner Kim Papalia told the Hills Reporter that the quarry is a 'dangerous environment' and said 'what otherwise looks like an oasis is a death trap'.
'This is not just about people trespassing on private property, there are risks relating to drowning and road safety,' he said, emphasising that there are heavy fines and even criminal convictions for trespassers.
