Australians can expect higher prices for fresh food and meat as a result of the bushfire crisis, but supermarkets have been warned to not put more pressure on devastated farmers.

Bushfire-affected farmers will also be given up to $75,000 to immediately repair their properties, with Prime Minister Scott Morrison promising at least $100 million to rebuild Australia's primary production farmland.

Agriculture Minister Bridget McKenzie estimated there were 19,000 farmers, foresters and fishers in the regions hard-hit by the fires and said customers would have to accept higher prices for some produce.

"In terms of prices of food, you might have seen reporting that supermarkets are letting the Australian public know that they'll have to pay more for their red meat. Yes, you will," she said on Tuesday.
