"How often have you woken up the morning after you've been drinking and cringed at the risks you took the previous night? And you don't have to be really drunk for alcohol to affect your judgement. Even a few drinks can make you take risks you would not otherwise have taken."
Murphy said those who had drunk alcohol often lost their ability to gauge the safety of a situation and were not able to take the right action.
"Staying on top of your drinking will help you to control risky or difficult situations."
Murphy said there would be extra teams of police working to catch drink drivers and stop people making silly decisions as a result of alcohol.
He said it was pleasing that 150 vehicles were stopped last weekend and no one was over the legal alcohol breath limit
However, a noticeable trend with young people was finding them in vehicles parked around the central business district pre-loading with alcohol before going into bars.
He said on Saturday night police issued 12 infringement notices for being in possession of alcohol in a liquor ban area. The fine is $250.
He said the best way to have a great time and to keep safe was to plan ahead.
