A survey of 10,000 people by the Flinders University found that 90 per cent thought the government should provide more funds for aged care.

Six out of 10 said public spending should be reallocated to aged care, and on average, that group thought it should be doubled.

A majority of income tax payers were prepared to pay more tax for satisfactory or high quality services.

The research, which was commissioned by the Royal Commission into Aged Care, was greeted with some caution by Smithton's Emmerton Park CEO Ian Adams.

"We welcome any inquiry and other people looking at funding to aged care, but it has to be taken on as part of a much greater picture.

"It's one thing for people to say they would pay more for aged care, and it's another when it comes out of their pay packets."

Respect CEO Jason Binder, who runs three aged care facilities on the North-West, said the community did need to work out how to support the needs of older people.

"We're looking at models of care in different countries as a bench mark of what we'd like to achieve, but they're getting 50-100 per cent more in funding."

Aged Care Minister and senator Richard Colbeck said the government knew the long-term viability of the sector was critical.

"The government has been focused on reforming the funding for residential aged care providers and supporting the sector to improve their business operations," he said.

"It has put record investment in aged care, from $13.3 billion in 2012-13, growing to an estimated $25.4 billion in 2022-23."

In response to the Royal Commission Interim report, the government has funded 10,000 more home care packages and more improved medication management.

It has also funded more support for dementia behaviour-management, he said.
