Dr Lowe appeared at Senate Estimates on Monday morning when he was questioned about the RBA's pandemic guidance issued in February 2021 and which stated the central bank would not raise rates until actual inflation was within the 2 to 3 per cent target.

The board said it did not expect these conditions to be met until 2024 at the earliest, however later backtracked on this advice, and has been increasing the cash rate since May.

Greens senator Nick McKim accused the governor of "inducing many Australians to take out mortgages in the belief that interest rates wouldn't rise until 2024".

"Do you think you owe those people an apology?" Senator McKim asked the governor.

"I'm certainly sorry if people listened to what we'd said and then acted on what we had said and now regret what they had done. So that's regrettable. I'm sorry that happened," Dr Lowe answered.

Prime Minister Anthony Albanese said he still had confidence in Dr Lowe as head of the Reserve Bank.

Mr Albanese noted Dr Lowe had apologised for the RBA statement but said "it's not up to me as Prime Minister to give an ongoing running commentary on the actions of the Secretary of the Reserve Bank".

Dr Lowe also said during his appearance, the RBA could have "chosen different language" to better explain the "caveats" and "conditionality" in the advice.

"That's a failure on our part. We didn't communicate the caveats clearly enough, and we've certainly learned from that and if you've had a look at the review for guidance, we're changing our approach to get across the caveats clearly enough," Dr Lowe said.

The head of the central bank said the situation in February 2021, when the guidance was issued was "dire".

"We wanted to do everything we could to help the country get through that," he said.

When questioned about why the RBA board raised rates before inflation met the target, Dr Lowe said he did not accept the RBA had acted prematurity.

"Our thinking was that we would need to see wage growth picking up from the low rate to 2 per cent because we'd had four or five years where wages were growing at 2 per cent and that clearly wasn't enough to deliver inflation and we wanted to see wages growth pick up close to 3 per cent."

The Greens senator later said in a statement, "while Dr Lowe has appropriately apologised, the actions taken under his leadership have led to a significant loss of trust in the RBA".

"This will take more than one apology to rebuild," Senator McKim said.

Inflation is currently at a record high at 7.3 per cent, but Dr Lowe said the Reserve Bank expects inflation will drop to the target 3 per cent by 2024 and that wage growth is "achievable".

"We want to see wages increase but we've got to be realistic when inflation is the highest it's been in 30 years," Dr Lowe said.
