Ms Nixon called the trip "reasonable" and commented that she was accompanying her husband, and that she had not had a holiday in about 12 months.

Mr Becquet defended the trip by saying they were invited to LA after a chance meeting with a Qantas executive.

[8] The head of the Office of Police Integrity, Michael Strong, sought information on the matter from Ms Nixon[9] at a time of calls for her to reimburse the airline for the cost of the trip.

Counsel assisting the commission, Rachel Doyle SC, questioned Nixon on issues such as a morning hairdressing appointment, a lunchtime meeting with her biographer and an evening dinner at a restaurant, all during the worst day of the bushfires.

[11] In October 2019 Nixon was selected as the chair of the Royal Australian College of General Practitioners (RACGP) board.

[20] She was appointed an Officer of the Order of Australia for "law enforcement, to women in policing, and to tertiary education" in the 2021 Queen's Birthday Honours.
