Environmental authorities have flown over the Victorian coastline to search for any more washed up whales, after the largest mass stranding since 1983 appeared in East Gippsland this week.
Twenty-seven pilot whales and one humpback were discovered on Tuesday at Croajingolong National Park.
Parks Victoria said the location is too remote to remove or bury the mammals, so they will be left to decompose where they are.
Anyone nearby will be notified of the decomposing whales via signage along the beach and a warning about higher shark numbers is in place until the carcasses have fully broken down, Parks Victoria said on Friday.
"This is a sad event and we have been very conscious of treating the animals humanely," incident controller Stephen Young said.
Two more pilot whales were found washed up on Big Beach, east of Mallacoota, on Thursday.
The pair have since been removed by front-end loader from the beach and transported away from the coast for burial.
It is not known if the pair found on Thursday are related to the larger group found on Tuesday.
The humpback whale found among the 28 was understood to have died in a separate incident, but washed up on the same shore.
Scientific sampling of all whales is being sent to the Melbourne Museum.
The events come as more than 140 pilot whales died in New Zealand after stranding themselves on a beach in the country's far south on Saturday night.
