Former Border Force boss Roman Quaedvlieg has taken his anger about being accused of "grooming" a woman to the prime minister.
Home Affairs Minister Peter Dutton used parliamentary privilege to accuse the former ABF chief of grooming a woman 30 years younger than him while in the role.
"Talk to anyone in the community & put together the words 'groomed' & 'girl' & see where their mind goes, let alone an ex-police officer, let alone one who has investigated offences against children," Mr Quaedvlieg tweeted on Wednesday.
Prime Minister Scott Morrison rejected suggestions the comment made Mr Quaedvlieg look like a pedophile.
"He has not done that. He has not done that at all," Mr Morrison said on Wednesday.
"What he has expressed, I think, is a great frustration at the false and repeatedly false claims that have been put forward."
Mr Dutton verbally attacked the 53-year-old ex-ABF boss in parliament after Labor quizzed the MP over claims he pushed for two Queensland police officers to secure jobs at the agency.
"(Mr Quaedvlieg) was, as commissioner, sacked from his position. He was a man who had groomed a girl 30 years younger than himself," Mr Dutton told parliament on Tuesday.
Mr Quaedvlieg, who was fired from his role after helping his girlfriend get a job, said Mr Morrison ignored his efforts to contact him.
"I politely expressed my dissatisfaction to the PM .... he read my message but didn't respond to me," Mr Quaedvlieg said.
The stoush between the two former Queensland police officers originally erupted over Mr Dutton's decision to grant visas to two au pairs held in immigration detention.
The Home Affairs department on Wednesday released more information about the au pair cases, revealing they received two of the 24 tourism visas Mr Dutton intervened to grant.
Mr Dutton was also accused of lobbying Mr Quaedvlieg to secure jobs at the ABF for two other former police officers, including one who is now an adviser in his ministerial office.
Mr Morrison is now also checking whether Mr Dutton recused himself from cabinet when childcare funding changes were decided.
Mr Dutton has a family financial interest in childcare centres, which are now receiving direct funding from the Commonwealth after law changes.
"I have always complied with the cabinet rules, I have declared any interests that I've had in any discussion," Mr Dutton told parliament.
"I have recused myself from discussions where that's been deemed appropriate."
