Former Liberal Party treasurer Philip Higginson is claiming vindication for his criticism of federal director Brian Loughnane amid the latter's expected departure from the job.

AM has confirmed Mr Loughnane is considering his position following Tony Abbott's removal as prime minister.

He is married to Mr Abbott's former chief of staff Peta Credlin, a relationship Mr Higginson labelled as a conflict as interest in a letter publicly venting strong privately held criticism of the power couple from elsewhere within the party.

In the letter he also questioned Mr Loughnane's ability to perform his "fiduciary duty" to the party.

"I wish him luck," Mr Higginson told AM in his first interview since the letter was leaked in February.

"I think he, like all of us, is human and to err is human."

He said Mr Loughnane's departure was a vindication of the points made in his letter.

"It was a prophecy that has come true, and that of course is vindicated too by the $1.5 million so alleged to have been embezzled by the Victorian state director," Mr Higginson said.

New South Wales state director Tony Nutt is being touted as a replacement for Mr Loughnane.

Mr Higginson said any future federal director must ensure higher organisational standards.

"There needs to be better financial governance, there needs to be better organisational governance so that we can look our donors in the face, our voters in the face, the members of our party in the face.

"I know the new PM understands this a whole lot better than the previous PM."

'He took a lot of bad advice from people who gave bad advice'

Mr Higginson is a former self-described confidant of Mr Abbott who helped with fundraising in the Warringah electorate in the early stages of his political career.

He and the former prime minister last encountered each other at a function two weeks before Mr Abbott was deposed as prime minister.

"We gave each other a very warm handshake and a very warm 'how do you do', and that will always be the case from my perspective," Mr Higginson said.

"He took a lot of bad advice from people that gave lots of bad advice."

Mr Loughnane declined AM's request for an interview.

In a statement to AM, federal president Richard Alston said Mr Higginson's claims had been considered by the party's federal executive earlier this year and it decided there were "no matters of concern not already being addressed".

He added the meeting expressed unanimous confidence in Mr Loughnane.

"The conflict of interest issue was raised late in the day after Mr Higginson had himself been criticised," Mr Alston said.
