Seven of the new cases are linked to known outbreaks, five are in hotel quarantine, five from routine testing and 13 are being investigated.

A health worker at the Orygen youth facility has the virus, Deputy Chief Health Officer Dr Annaliese van Diemen told reporters on Friday.

A McDonald's worker has also been confirmed as having coronavirus and is linked to the Wollert outbreak, she said.

There are 183 active cases in Victoria with six in hospital. More than 1700 people have recovered from the virus in the state.

The new figures come as Victorian tourist centres and accommodation providers prepare for an influx of tourists over the school holidays, which kick-off after classes finish today.

Tourism leaders across the Ballarat region are pleading for tourists to respect social distancing and hygiene measures.

Ballarat still has 11 confirmed cases of COVID-19 since the pandemic began a few months ago, while Moorabool (3), Hepburn (2) and Golden Plains (1) remain steady.

On Thursday, Premier Daniel Andrews issued an open letter to all Victorians, saying once again the state finds itself on a 'knife's edge' yet again.

"We don't want to have to move to local lockdowns," he said.
