There are conflicting claims about a visa application of a Papua New Guinea member of parliament, Chris Haiveta, to travel to Australia.
Mr Haiveta's office says he has been refused a visa to fly to Cairns on a personal matter.
However, the Australian immigration department denies that he has been refused a visa.
And the Australian high commission in Port Moresby declined to comment.
Last month, Canberra placed a ban on all ministerial contact and travel between the two countries after the clandestine flight of the suspended Solomon Islands attorney general, Julian Moti, from PNG to Solomon Islands.
Australia had been seeking to have Mr Moti extradited on child sex charges.
