Bill Shorten has been flat out the last few days, flooding airwaves with speeches, interviews, talk-show appearances (this week's ABC Q&A) and doorstops.

It's resulted in him wandering into territory outside his normal cabinet duties as minister for government services and the NDIS.

Asked at an impromptu corridor press conference in parliament house this morning whether he agreed with the Reserve Bank of Australia's view that the economy is essentially running too hot,  Shorten vehemently disagreed.

And then, in unusually blunt language for a government minister, offered unsolicited advice to the independent central bank.

Telling reporters that the RBA is not "immune from being disagreed", he went on to reprise former governor Phil Lowe's infamous signalling during the pandemic that official interest rates would stay low for years.

"Perhaps if we'd disagreed with the former governor's statement that rates would be historically low for years, some people wouldn't be in the financial predicament they're in now," he said.

"I do not believe the economy is running hot.

"The way to deal with it though, isn't to push the nation into recession with higher and higher interest rates."
