While the submarine was at sea to film for Defence Force Recruiting, the Department of Defence admitted Mr Noonan's decision to bring his partner on board was 'not routine'. Mr Noonan retired from Defence in September 2022 after 38 years in the force While the submarine was at sea to film for Defence Force Recruiting, the Department of Defence described Mr Noonan's decision to bring his partner on board as 'not routine' 'Defence is advised that Mr Noonan proposed marriage to his partner during the sea ride,' a spokesperson said. While their romantic getaway didn't break any rules, the spokesperson added 'it is not routine for Defence members to take a civilian partner, spouse (or) relative on an overnight sea ride'. In a move unrelated to the indiscretion, Mr Noonan was replaced as navy chief five days later by Vice Admiral Mark Hammond. The proposal was slammed by former digger and Coalition defence spokesman Phillip Thompson who argued it was evidence of a double standard between those of various ranks in the force. 'If it had been an enlisted soldier in the lowest rank, they would definitely be in trouble for (bringing) someone on to a military equipment or base and they would be reprimanded,' he told Daily Mail Australia. 'I think there is a double standard.' Mr Thompson said the move had also left members of the Navy in an 'awkward position', learning about something that 'wasn't a good look' months after it happened. The proposal was slammed by former digger and Coalition defence spokesman Phillip Thompson (centre) who branded it an 'abuse of power' and called out the double standard between those of junior ranks 'The Navy is very professional and are very good at their job,' he said. 'And the leader of the Navy has done something that isn't right and can be viewed poorly.' Mr Thompson said a process needed to be put in place to prevent any further incidents from happening. 'Military equipment isn't anyone's personal equipment, it's definitely not the chief of navy's love sub,' he added. 'I think there needs to be a process for when the highest ranking person in your branch of defence force does something that is not in line with its best practice or for what the equipment is used for.' Mr Noonan retired from Defence in September 2022 after 38 years in the force. Mr Noonan had granted approval for his now-fiance to come on board the submarine He attended Royal Australian Naval College in 1984 and after a distinguished career that included coalition anti-terrorism operations, was appointed Deputy Chief of Navy in 2016, then Chief of the Navy two years later. Ms Heighway congratulated him on his career in a Facebook post at the time. 'Michael Noonan… congratulations on your service to our county, your selfless leadership and on inspiring the next generations that will selflessly serve to protect our country. 'So to say, this person, Michael Noonan, I adore and am truely inspired by would be an understatement.' Daily Mail Australia has sought comment from Mr Noonan.
