Military personnel look set to be deployed to Victoria's bushfire crisis after Prime Minister Scott Morrison confirmed on Tuesday that the ADF was working with the state's Country Fire Authority.

Premier Daniel Andrews asked Mr Morrison for military assistance amid Victoria’s “very significant fire event” with four people unaccounted-for in the blazes and thousands still in danger in the towns of Corryong in the north-east and Mallacoota in the south-east.

Emergency Victoria confirmed that there has been heavy loss of properties across East Gippsland with firefighters still unable to get into large areas of the fire zones to assess damage or loss of life.

The Premier said the Australian Defence Force assistance could be Naval vessels to get supplies to isolated communities or heavy-lift aircraft to supplement the state’s own air fleet, but no decisions on deployment had been yet been made
