A fire broke out at Viva Energy's 120,000 b/d Geelong refinery in Australia overnight, and was still burning as of 5:27am local time (15:27 GMT) on 16 April.
The incident was first reported at 23:07 local time on 15 April with onlookers describing explosions and flames. The fire is contained to the motor gasoline plant area and involves liquid fuels and gases, Fire and Rescue Victoria said at 4:58am.
Smoke is still affecting northern suburbs of the city of Geelong, including Corio where the plant is located.
Viva said there is no immediate impact on fuel supplies, according to Fire and Rescue Victoria.
The refinery supplies 10pc of Australia's fuel and is the larger of two remaining in the country after a raft of closures since 2009, along with Australian refiner Ampol's 109,000 b/d Lytton site in Queensland state.
Geelong is Australia's only refiner of jet fuel, aviation gas and bitumen and has been considered even more critical to the nation's fuel security since the outbreak of the US-Iran war in late February.
Viva produced 99,000 b/d at Geelong last year and will run the refinery until at least 30 June 2030 under a fresh subsidy deal, struck with the federal government last month.
