One of Scott Morrison's final acts as Prime Minister was to instruct the Australian Border Force (ABF) to publicise an interception of a suspected asylum seeker boat on election day.
As voters were going to the polls on Saturday, the Operation Sovereign Borders Commander issued a rare statement announcing a "vessel has been intercepted in a likely attempt to illegally enter Australia from Sri Lanka".
The ABC can reveal that the highly controversial move during the election caretaker period followed a direct request from the Prime Minister's Office to publicly release details of the sensitive ABF operation before it had been completed.
About the same time as the prime minister spoke, the statement from Rear Admiral Justin Jones, the Operation Sovereign Borders Commander, appeared on the ABF's website, warning that the Australian government's policy on illegal boat arrivals "remains unchanged".
The unusual disclosure of operational "on water matters" is now subject to an inquiry by Home Affairs Department Secretary Mike Pezzullo, ordered this week by the new Labor government.
Officials with knowledge of the events that occurred on Saturday say the Department of Home Affairs first examined the legality of issuing a statement during an election campaign because of concerns it could breach caretaker conventions and politicise the public service.
Eventually, it was decided that a statement could be issued by the commander, a move that has been privately criticised by Rear Admiral Jones' colleagues in the Australian Border Force as well as the Australian Defence Force.
The ABC has approached former prime minister Scott Morrison, specifically to ask why his office requested the Australian Border Force to reveal the boat interception, but he has declined to comment.
On Tuesday, Rear Admiral Justin Jones confirmed the boatload of asylum seekers intercepted near Christmas Island on election day had now been returned to Sri Lanka after appropriate assessments.
