The federal government has apologised to Australian veterans and their families for failings in the way the defence forces and veterans affairs department have operated.
The apology comes after the Royal Commission into Defence and Veteran Suicide released its 300-page interim report and 13 initial recommendations on Thursday.
"To people that have felt they have not got the treatment that they deserve ... I apologise for that," Veterans Affairs Minister Matt Keogh told reporters in Canberra.
"It wasn't under our watch, but as the government of this country, veterans always deserve the best and we should be delivering that."
Australians want to see veterans treated better but issues could not be fixed overnight, Opposition Leader Peter Dutton said.
"Certainly from my perspective (the coalition) provided every support, not just through increased funding but additional support through services, mental health services, and the like," he told reporters in Sydney.
"There is enough blame to share across both sides of politics, but I think this is not an issue about politics ... we should be doing more as a country to provide support to those who defend us and keep us safe."
The commission recommends urgent changes need to be made to Australia's defence personnel support network and that the backlog of veterans claims be cleared by March 2024.
It also recommends the government introduce legislation to parliament to simplify and harmonise veteran compensation and rehabilitation.
The coalition expects to support the government as much as it can in that process, opposition veterans spokesman Barnaby Joyce said.
"I don't expect veterans' access to the support they're entitled to, to be delayed by unnecessary reasons," he told AAP.
"It's vitally important that this process takes place, I was always a supporter of a royal commission and it was the coalition that brought it about in government."
While Mr Keogh said he didn't have a time frame for when the backlog would be cleared, he wants it done as soon as possible.
The government has allocated 500 additional staff to the department to help get through the claims, he said.
"All people who put on a uniform and sign up to serve our nation ... they deserve the best support while serving and after they transition to civilian life," Mr Keogh said.
"This is particularly the case when individuals encounter mental and physical injury. This is a commitment that we owe our defence personnel, veterans and their families."
Mr Joyce wants more details on the funding for and tasks of the additional staff and expects the government to provide information in the October budget.
"A number is important but the process of what they actually do is vital to understand the issue is being addressed," he said.
He also called for the veterans portfolio to be returned to cabinet.
"Having veterans affairs languishing in the outer ministry, with the minister for republic, does not show proper respect for the importance of the issues in need of reform," Mr Joyce said.
Meanwhile, Mr Keogh said he had confidence in the veterans affairs department to assist defence personnel as much as possible.
A formal response from the government to the commission will be provided in the coming months.
"We recognise the importance and the significance of this report ... It is vital that these (recommendations) are now addressed as a priority," Mr Keogh said.
