Here's why alcohol and being in the water, don't mix!
Two men - one aged 19 and the other in his 30s - have drowned after drinking with another mate in a Melbourne park.
The pair went for a a drunken evening swim in Redleap Reserve at Mill Park on Sunday night, but quickly got into trouble.
Their mate had also entered the water at about 530pm, trying to save the pair but when he started to struggle he got out and raised the alarm.
Resident Nathan Henderson - also a surf-life saver - grabbed his surfboard and paddled into the lake with police in an attempt to save the two men.
"A police officer arrived and jumped in. So I sprinted home, grabbed a surfboard so we had something to float on... and then we started searching the lake," he told Nine News.
Witnesses say they heard screaming for help.
Police confirmed they retrieved the mens' bodies from the water between 9.20pm and 10pm on Sunday.
Senior Sergeant Mark Smith said the men were affected by alcohol.
"Unfortunately because of the effects of alcohol, two of them have got into trouble while swimming across the lake," he said at the scene.
