If a celebration gets out of control in one State, the penalties could include massive fines and even jail terms.

The tough new party laws were introduced in Western Australia two weeks ago. Now, if a gathering of twelve or more people gets out of control, the host can be jailed for up to twelve months and fined up to $12,000 if their guests behave badly.

Party goers who refuse to move on can also be arrested on the spot.

According to WA's Acting Police Minister John Day "people who act sensible, decently and with normal common sense - most people - would expect absolutely nothing to fear from this legislation at all."

He acknowledges that "some people might express the concern that this is a power that is excessive, it's symptomatic of something of a totalitarian sort of state, but that is simply not the case."

The laws have come about as a response to a string of ugly teenage parties, like on in the suburb of Piarra Waters, where a small gathering swelled to 500 after details were posted on social media.

Police were pelted with rocks and bricks, and even flares were let off.

Now police are being proactive by checking social media for potential problems. Last night they ended a Perth party which had been advertised on Facebook before it began.

"I think if any other states in Australia have the same sort of problems that we've had in Western Australia, where there are serious problems, serious fear and alarm, then this sort of legislation is appropriate to consider as a response," Day said.

President of the Australian Council for Civil Liberties, Terry O'Gorman, says it's likely the party laws will be adopted throughout Australia.

However he argues that police already have sufficient powers to deal with unruly gatherings and guests.

"One of the most objectionable aspects of this rule is that it imposes a criminal offence on a person who organises a party, and that includes parents in respect of juvenile parties, if a party gets out of control," O'Gorman said.

"Now the fact is in no other area of the criminal law is the individual responsible for what other people do, and that is fundamentally wrong."
