The prime minister, Scott Morrison, says that Australians should prepare to receive information about "bruises" so that they leave the royal commission and become care for the elderly.
Mr. Morrison announced the royal commission on Sunday, after terrible cases of elder abuse.
"I think we should prepare ourselves to get pretty blunt information about the way our loved ones, some of them have experienced some real abuse," Morrison told reporters on Sunday.
"I think it's going to be difficult for us to deal with that, but you can not get past that."
The commission received the support of the main groups of the sector, but they indicated that there were already a series of reviews in the sector.
It occurs when the number of Australians moving into residential care will increase sharply as the country's population ages.
"We are committed to giving Australians greater access to the care that supports their dignity and recognizes the contribution they have made to society," said Mr. Morrison.
The decision was triggered in part by the Oakden nursing home scandal in South Australia.
The home was closed a year ago after it was revealed that elderly patients with dementia had been abused for years.
The prime minister said he could no longer ignore the alarming number of elderly care operators who "flouted the law and put lives at risk."
There was a 177% increase in the number of nursing homes where a serious risk was identified for residents in the last fiscal year, according to new government figures.
There was a 292 percent increase in the number of facilities that refused to comply with the rules.
Leading Age Care Services Australia, Aged and Community Services Australia and the Council on the Aging said they welcomed the review.
But Leading Age Care CEO Sean Rooney said the royal commission should not impede urgent changes.
"We must move forward with the key issues of the workforce and funding, and not lose sight of the improvement of the system at this time," he said.
The executive president of COTA, Ian Yates, echoed that sentiment.
"While the commission is doing its job, the Morrison government must continue to focus on the implementation of recommendations from a series of consultations to the sector in recent years," he said.
Aged and Community Services Australia, which represents some 700 nonprofit providers, said the real commission is an opportunity to have a "broader conversation" about what the community wants out of care for the elderly.
Labor leader Bill Shorten, who previously said there is a "national crisis" in elder care, said the investigation was pending.
