Victoria has recorded 450 new COVID-19 cases, a big jump in the state’s infection numbers.

The positive cases were detected from 42,765 test results and contact tracers have only been able to link 75 to existing cases.

Authorities have been increasingly concerned about the spread of Delta in Melbourne’s north and west, with at least 299 of the 334 cases reported yesterday linked to those areas.

New COVID exposure sites have popped up in regional Victoria in Lorne and Daylesford a day after areas outside Melbourne, except Shepparton, exited lockdown.

The latest Commonwealth data shows 64.5 per cent of Victorians over the age of 16 have had at least one vaccine dose, while that figure is 40 per cent for those who have had both doses.

As Melbourne remains in lockdown, millions in regional Victoria are enjoying their first weekend out of lockdown.

Shepparton is the only place which remains under lockdown rules.

MOTHER PRAISED

Meanwhile Queensland Premier Annastacia Palaszczuk has warned parts of south-east Queensland may have to go into lockdown within days after five new local cases were reported on Saturday, but for now the region will remain open.

Ms Palaszczuk said the “really good news” was that all five new cases were from the same family.

Ms Palaszczuk and chief health officer Jeanette Young said the virus was carried by a visitor from NSW.

They praised the mother of the family for getting her daughter tested so quickly after she got a headache, giving the authorities a better chance of restricting the spread of the virus.
