Nightclub releases security footage of COVID-positive man on dancefloor

The Adelaide nightclub forced to close its doors after a COVID-positive man spent the night partying there has released CCTV of what it says is of him on the dancefloor.

Earlier this week, Ralph MacIntosh was fined $600 for breaching COVID-19 rules in December, forcing hundreds into isolation over Christmas.

Today, Loverboy nightclub posted and later deleted security footage set to the song "D---head" by UK singer Kate Nash.

Before going to the venue on December 17, MacIntosh had undergone a PCR test.

But he partied, Snapchatted and drank at the venue.

At one stage, MacIntosh appeared to lob a glass into the crowd as he danced with others.

At the time there was an unopened text message on the teenager's phone confirming he had tested positive to COVID-19, which he did not read until the next morning.

His attendance at the nightclub forced 150 people into isolation over Christmas.

Loverboy's management posted the video as part of a dispute over compensation.

The owners said they lost $60,000 and all their staff were in isolation for Christmas.

MacIntosh's lawyer today said posting the video was irresponsible but he doesn't intend to speak to the club about it.

The nightclub's claim for compensation has been rejected.

MacIntosh is from one of Australia's wealthiest families, which is associated with a giant wool exporter.

Premier Peter Malinauskas said he's seen the video and agreed the owners had a right to be angry.

"He had one of the best levels of legal representation that money can buy in our state and he walked away with a $600 fine… Loverboy had a $60,000 consequence, other people missed out on Christmas," Mr Malinauskas said.
