Mr Farnham’s manager Glenn Wheatley slammed the actions of protesters, saying the song was being used against the wishes of Mr Farnham.
“I’m personally concerned people will hear the song and think John Farnham is personally endorsing these protests, and in this case it’s not right," Mr Wheatley told The Age.
"It’s something that John and I do not condone, the use of that song, particularly in a time in Melbourne where we are in stage four lockdown."
"Really, the last thing we should be doing is protesting, no one should be hitting the streets en masse, endangering people’s lives and livelihoods."
The manager also criticised the use of the song at far-right demonstrations.
“It was not meant to be a protest song, it was meant to be used as an inspirational song for nations and for people, not in a situation of what was an illegal protest,” he said.
SBS News has contacted Mr Wheatley for comment.
Two protesters were arrested by Victoria police on Sunday, with another six issued infringement notices.
On Saturday, sixteen arrests were and 21 fines issued after up to 100 people protested in the beachside suburb of Elwood.
On Monday, Victoria recorded just 11 new coronavirus cases, the state's lowest tally since 16 June.
Victorian Premier Daniel Andrews said the continued decline in infections is proof the lockdown strategy is successful in curbing the virus spread.
