More than 450 people were charged across WA during a police blitz on drunken violence and anti-social behaviour.
Operation Unite, an Australian and New Zealand operation, targeted entertainment precincts as part of a no-tolerance approach by police ahead of the busy summer period.
On Saturday night, 289 people were charged with 336 offences, including assault, assaulting a public officer, disorderly behaviour and excess 0.05 and excess 0.08.
On Friday night, 183 people were charged with 210 with 113 liquor infringements and 152 traffic infringements issued.
Over 12,000 roadside breath tests were conducted over the weekend with 48 people instantly losing their licence.
In Northbridge and the Perth CBD alone, almost 70 police officers flooded the streets for a highly visible presence throughout both nights.
Police figures have previously shown that 70 per cent of all police work was related to excessive alcohol consumption.
Last year’s December operation netted more than 800 people charged with similar disorderly conduct offences.
In Queensland, police cracked down on alcohol-fuelled crime ahead of Christmas, resulting in more than 400 charges.
More than 1200 uniformed and plainclothed police flooded “hot spots” across that State, targeting alcohol misuse, violence and anti-social behaviour in the past two nights as part of Operation Unite.
In NSW, A 13-year-old girl was hospitalised and almost 550 people were arrested during the weekend crackdown on alcohol-related violence.
NSW police said arrests were up in the state.
While last year’s blitz saw more than 380 people arrested over two nights, this year almost 550 people managed to get themselves “so drunk, or so out-of-focus that they got themselves in strife and got themselves arrested“, Deputy Commissioner Nick Kaldas said today.
"What we are seeing more and more is that when people do get out and don’t have a plan for getting home they end up presenting themselves as victims rather than offenders as well,” he told reporters in Sydney.
Among the "victims" was a 13-year-old girl who was found by police passed out in the backyard of a Bellevue Hill home in Sydney’s eastern suburbs.
Police said the girl had allegedly consumed a "large amount of vodka" at a party of more than 250 teenagers.
The girl was taken to Randwick Children’s Hospital in a stable condition.
At Kings Cross, Sydney’s nightclub district, three men were arrested after a brawl broke out at around 1.45am (AEDT).
Meanwhile, in Ballina in northern NSW, a police officer was allegedly assaulted after a man was refused entry to a licensed hotel due to intoxication. The 36-year-old is expected to be charged with assault police and resist arrest.
Mr Kaldas said although Queensland has had a “marked drop in arrests“, NSW did not greatly differ from other Australian states and territories
In Queensland, 28 people were arrested for assault offences, 119 people were caught drink driving, 169 liquor infringement notices were issued and 912 licensing breaches found at venues.
Deputy Commissioner for Specialist Operations Ross Barnett says Operation Unite showed police were serious about preventing alcohol-fuelled violence.
“The operation is about making people feel safer and more secure - not curbing their enjoyment,” he said in a statement on Sunday.
“Alcohol misuse, violence and anti-social behaviour is a problem that affects the entire community.”
He said he had a simple Christmas message: “Go out, have a good time, but don’t let your fun get out of control, and when you are drinking, do not drive”.
Victorian police arrested more than 160 people across the State.
Provisional statistics from Operation Unite show 166 people were arrested. Of those arrested, 105 were drunk, while 29 assaults were detected, police said.
The figures indicate a slight decline in arrests compared to Operation Unite 2011, in which 180 Victorians were arrested, including 158 for public drunkenness.
