Seven workers across two power stations in Victoria's east have tested positive to coronavirus in the past week.
It comes as local health authorities work to tackle regional Victoria's largest COVID-19 outbreak in the Latrobe Valley, which has recorded more than 330 active cases.
Nearby, non-essential workers at a gas and oil platform off the Gippsland coast have been forced to evacuate, after two staff members became infected with the virus.
Power industry workers test positive
Five workers at the Yallourn Power Station returned positive rapid antigen tests at the weekend.
The plant's owner, Energy Australia, said the company had identified close contacts who were ordered to isolate and deep cleaning had been carried out at the site.
Nurses conducted a further 128 rapid tests on Saturday but no other positive cases were found.
Meanwhile, two workers at Traralgon's Loy Yang A power station have also contracted the virus.
Its operator, AGL, said the matter had been referred to WorkSafe for review.
The cases have emerged as Latrobe City battles regional Victoria's biggest outbreak.
But promising figures released yesterday by the state's Department of Health show Latrobe city had surpassed a major vaccination milestone, with 70.1 per cent of its residents now fully vaccinated and 94 per cent with a least one dose.
Dozens evacuated
Oil and gas company Esso Australia has removed non-essential workers from its Marlin A and B platforms in the Bass Strait after a crew member became infected with COVID-19.
They are the second member of Esso's offshore workforce to test positive after a worker on the Tuna platform was reported to have the virus on Sunday.
The first case prompted the company to evacuate 35 workers from the platform, flying the crew to Sale to undergo immediate testing.
A company spokesperson said in a statement that Esso had COVID-safe protocols in place "to ensure continuity of supply and these have been enacted. There is no risk to gas supply."
