POLICE have arrested more than 160 people across Victoria in a holiday season crackdown on public drunkenness.

Provisional statistics from Operation Unite, which occurred across all Australian and New Zealand police jurisdictions on Friday and Saturday nights, show a total 166 people were arrested.

Of those arrested, 105 were drunk, while 29 assaults were detected, police said.

Police conducted breath tested more than 1000 drivers, with 13 returning positive results.

The figures indicate a slight decline in arrests compared to Operation Unite 2011, in which 180 Victorians were arrested, including 158 for public drunkenness.

Queensland police have cracked down on alcohol-fuelled crime ahead of Christmas, resulting in more than 400 charges.

In the state, 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 said 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".
