Parents who defied defied social distancing rules to throw their eight-year-old son a birthday party at their Melbourne home have been slapped with a $1,652 fine.

At least 16 parents and children were seen standing outside a home in Beaumaris, 20km south-east of the CBD, on the weekend.

Some of the party-goers appeared to be breaking the 1.5metre social distancing rule as well as flouting guidelines banning public gatherings of more than two people.

The behaviour was condemned by neighbours, with one witness saying she saw as many as 50 people attending what she thought was an 'auction'.

Victoria Police issued the fine to the party's organiser but none of the people in attendance were hit with an infringement.

Police arrived to see the home covered in birthday decorations, balloons and even a sign that read: 'This way to Isaac's party'.

The party was reported to police by onlookers frustrated with the 'arrogant' parents.

One neighbour, Claire May, said she was horrified to see so many people together.

'It looked like an auction there were that many people. I counted fifty,' she told Seven News.

'I was angry, very angry.'

Another witness said the party-goers should be ashamed.

'You're not an exception. I say shame on you that you put yourself in that situation,' Juliana said.

Police arrived at the home after the celebrations had wrapped up.

The remaining parents were ordered to leave by police, while the event organiser was fined $1,652 on the spot.
