Prime Minister Tony Abbott says he was "very happy" to be met by the ambassador to France and his partner last month, despite a report suggesting the incident led to the ambassador offering his resignation.
Fairfax reports a "bizarre incident" occurred when Mr Abbott arrived in Paris on Anzac Day.
It said ambassador Stephen Brady was on the tarmac with his long-term partner, Peter Stephens, when the Prime Minister's travelling party sent an instruction that Mr Stephens should remain in the car.
The arrival was not a public event.
The ambassador reportedly refused and following the incident, offered his resignation to the Department of Foreign Affairs and Trade (DFAT).
His resignation was not accepted.
The Prime Minister's office did not deny the incident took place, but said in a statement: "The Prime Minister was very happy to be met by ambassador Brady and his partner when he arrived in Paris last month."
The ABC has been told it is protocol for an ambassador's partner or spouse to be part of a welcoming party when the prime minister is travelling with his or her spouse.
However, Margie Abbott did not travel with the Prime Minister to Paris.
It would be unusual for a Prime Minister to choose the members of a greeting party at an airport.
The decision is most often made by staff or the foreign affairs department, according to protocols.
In a statement, Opposition Leader Bill Shorten said, "I sincerely hope this isn't true".

Communications Minister Malcolm Turnbull has been working assiduously to keep a lid on the simmering disquiet about the National Broadband Network (NBN). No news is good news, as far as Turnbull is concerned, but it would be too early for him to claim that he has completely nullified all opposition to the Coalition’s multi-technology mix (MTM) NBN.

The government’s pre-election NBN related commitments have fallen by the wayside and Turnbull is yet to make any attempt to introduce legislation to repair what he described in 2011 as “a very complex Gordian knot of [Telstra] contracts and legislation that is going to be very hard to unpick." It should be apparent by now the government is attempting to utilise regulation to implement the changes necessary for the MTM NBN rather than attempting change through the Senate
