South Australia's changes in their liquor laws will take effect next week which will give more support to licensees dealing with drunks.

People will be able to take home from restaurants unfinished bottles of wine under the new changes that will take effect from Monday.

Gail Gago, SA Consumer Affairs Minister, says licensees will have a clear definition of what intoxication is.

The new description states that people who appears to have speech, balance, coordination or behavior impairment and there's reasonable belief that impairment is due to alcoholic consumption is required by law to refuse the sale or supply of alcohol, she said.

We are also introducing new rates of fines for a range of different offences, so these new measures are about to improve the responsible consumption of alcohol and make our pubs and clubs enjoyable and safer places to be.
