HAVE fun responsibly on Australia Day is the message police are sending to residents and visitors.

Police are taking a zero tolerance approach to alcohol and antisocial behaviour on the Mornington Peninsula on Thursday.

The tough approach follows out of control youths going on the rampage in Mornington two years ago during Australia Day celebrations.

Police will be out in force to manage celebrations across the peninsula, including additional crews from Frankston, Carrum Downs and Melbourne.

And there will be $100 infringements handed out to people found with alcohol in sealed or unsealed containers in public areas.

"Our aim is to minimise incidences of anti-social behaviour, alcohol and drink-driving," Mornington's Acting Senior Sergeant Steve McRae said.

"Safety is the biggest priority. Last year the day's celebrations ran very well with increased police presence and additional breath testing."

Acting Senior Sergeant McRae said police wanted to ensure Australia Day celebrations were enjoyed in a family-friendly environment. "We are hoping everyone enjoys themselves responsibly," he said.

Extra public buses will be put on to help people get to celebrations safely. Police advise people to take public transport or designate a driver.

There will be events happening across the peninsula, with the Mornington street parade an annual favourite for spectators, as well as flagraising ceremonies, entertainment and fireworks, sponsored by the Weekly.

The Mornington Peninsula Music Network has developed a family music program in Mornington Park from 6.30-9pm and

Mt Martha Lifesaving Club will hold its annual fund-raising event - the Mt Martha Australia Day Swim.

Swim manager Craig Hood said it was a great community event with a host of events for participants. "The money raised from entry fees goes towards new equipment and training programs for our lifesavers," he said.

There are events for all levels, kicking off with five-kilometre 'crazy' swim at 8am, a nippers 200-metre swim at 9.30, a 400-metre novice swim at 9.45am and the 1.2-kilometre MMAD swim at 11am.

Swimmers assemble at the Mt Martha Life Saving Club and the main event follows a challenging 1.2-kilometre course back to the club. This year, there will also be a non-wetsuit category for any brave ocean swimmers.

There will be plenty of action on the beach, with a roving MC and spot prizes given away throughout the day.

Swim registration forms can be found at mmadswim.com or swimmers can register on the day.
