The first so-called drunk tanks have opened in Sydney as part of the New South Wales Government's crackdown on alcohol-related violence.
Police are able to take drunk people to the sovering-up centres if they refuse to go home, the ABC reports.
Assistant Commissioner Mark Murdoch says the centres are reserved for violent or nuisance drunks and well-behaved revellers have no need to worry.
Police started operating the tanks in Sydney city and Randwick on Friday.
The first tenants were five men aged from their late teens to their early twenties, each fined $A200 on their release the following morning.
The death of Thomas Kelly in July last year prompted the introduction of tough new conditions on some venues, including a ban on the sale of shots after midnight.
Kelly was king-hit while walking along the popular nightclub strip with his girlfriend and died in hospital two days later.
