Smaller, independent operators are hoping Monday's mid year budget outlook will deliver more money for the sector.

It's feared up to 15 per cent of providers would be forced to close if their finances don't improve before July.

A coalition of aged care charities, including Uniting Care Australia, are calling on the government to put more money into building the aged care workforce.

They also want more home care package funding, with Australians facing a 120,000-person wait list.

The government should also include community infrastructure strategies in their drought response to help aged care services in rural areas.

One operator says the government would be forced to look after thousands of residents if rural aged care homes started to collapse.

Aged Care Deloraine chief executive Charlie Emmerton said his Tasmanian home runs on a shoe string, putting enormous pressure on his staff.

"There is a real need for additional funding now," he said.

"The big players will not come to the bush, there's no money in it."

He said he knew there was likely to be more response from the government at the end of the Aged Care Royal Commission but the sector couldn't wait.

Victorian aged care operator Darren Midgley said one of the greatest challenges facing the sector was inadequate funding.

Mr Midgley, who is the chief executive of Chaffey Aged Care in northwest Victoria, said some were going over budget to provide quality care.

"There needs to be an interim injection of targeted funding to sustain residential aged care," he said.

Health department data says there are nearly 200 aged care providers caring for up to 50,000 older Australians at high risk of financial collapse.

Treasurer Josh Frydenberg will deliver the mid-year budget review on Monday, with experts saying any loosening of the purse strings is unlikely with weak economic growth and government keen to pursue a surplus.
