Inspector Shane Cashman, said efforts had been focused further north today.
"We've gone further north from Walhalla towards Fiddlers Green, we're covering all the tracks, off roads, camping grounds and we've gone over all the huts again this morning just in case the missing people took some cover overnight" Inspector Cashman said.
Friends and family are actively involved in the search, while specialist resources have also been called in.
"We have specialist police resources, we have the ability to go into some hard tracks and four-wheel driving, we've also got some aerial support as well" Inspector Cashman said.
"its a search area of over one thousand square kilometers that we have to cover, and we're widening it as we go through and clear areas, so its a large area and an extensive search"
"From a search point of view, we're looking at have they become bogged, have they become trapped in the snow, have they had a vehicle issue that has stopped them from being able to drive, so we will just keep on going until we find them or the car".
It is believed that the missing pair have some supplies and sleeping bags, if they remain unfound they face a sixth night of cold conditions.
Anyone with information is urged to contact Crime Stoppers on 1800 333 000.
