Victoria has celebrated its first 'Double Donut' day in weeks with a cheeky nod to exuberant Australian swim coach Dean Boxall.

The state recorded zero locally and overseas acquired coronavirus cases on Wednesday, just days after Victorians were lifted from their fifth lockdown.

The state's chief health officer Professor Brett Sutton expressed his delight by sharing a meme of Boxall's crazy post-race celebration at the Tokyo Olympics.

The Australian coach made headlines around the globe last week following his wild antics when his swimmer Ariarne Titmus upstaged US legend Katie Ledecky to win gold in the 400 metre freestyle.

Boxall has captured by television cameras ripping his face mask off as he punched the air in excitement and shook the glass barrier.

Dr Sutton's cheeky tweet was soon inundated with comments from fellow Victorians celebrating the news.

Many others saw the the funny side.

'F*** yeah!' One commented, referring to Australian swimming gold medallist Kaylee McKeown's F-bomb on live television post-race.

All of Victoria was plunged into a two week lockdown last month after an outbreak of the highly-contagious Delta strain crossed the border from NSW.

More than 20,000 Victorians were plunged into a 14 day isolation after being deemed as close contacts

Victoria currently has 99 active Covid-19 cases with 2,000 close contacts still in self-isolation.

More than 30,000 Victorians came forward for testing on Tuesday while another  17,612 rolled up their sleeves for the Covid-19 jab.
