Police will patrol parks, beaches and pubs in Melbourne's south for one of the biggest tradie party days and nights of the year.
Police say many of the 25,000 manufacturing workers in the City of Kingston will be out to lunch or at Christmas parties on Friday as many factories close for the traditional break between Christmas and New Year.
The City of Kingston includes the suburbs of Mentone, Mordialloc and Dingley and has one of the highest numbers of manufacturing workers of any Victorian municipality.
Mentone Hotel functions manager Shae Ffrench said this was the biggest time of the year for party bookings. The hotel had one tradie Christmas lunch booked on Friday, but hosted three the day before.
"Tradie groups can get a bit rowdy in their celebrations, but we have talked to our security about managing that," Ms Ffrench said.
She said there had been Christmas parties all week and about 20 per cent were trade companies. Others included energy companies, office workers, hospital staff and a doctors' group.
Inspector Martin Phillips, of Kingston Police, said in the past anti-social behaviour and street offences had been a problem.
He said police had worked with local employers in the past three years to promote safer behaviour at parties such as providing food and encouraging responsible alcohol consumption as part of Operation Tradestamp.
"We have had a steady decrease in anti-social and street offences over the years," Inspector Phillips said.
Inspector Phillips said Operation Tradestamp also reminded employers they were responsible for their workers' behaviour, even if the party was off-site.
He said fights between co-workers were common at work functions. He said the blitz would include random breath testing.
“We will also have a number of officers focused on road safety so if you are driving through then you can expect to be breath-tested,” Inspector Phillips said.
