Hook has secured the top job after stepping down as chief executive of Deloitte Asia Pacific in Singapore earlier this year to head back to the United States.

"I thought I had retired last June and the search team [for Brisbane 2032] called in July and I said 'I would go back to work for that'," Hook told The Australian Financial Review.

"We moved back from Singapore to the US in July and now I’m excited about moving back to Brisbane.

"The husband is out house-hunting right now.

"I think it’s a once-in-a-lifetime opportunity for me as a career perspective and certainty for Brisbane and Australia."

Hook first moved to Australia in 2009 before becoming chief executive of Deloitte Australia six years later.

She then took on the same role for Deloitte Asia Pacific after relocating to Singapore in 2018.

Brisbane 2032 President Andrew Liveris said Hook’s experience with the professional services firm, which joined the International Olympic Committee’s flagship The Olympic Partner sponsorship scheme earlier this year, would be key to preparations for the Games.

"Her track record at Deloitte Australia and Deloitte Asia Pacific speaks for itself," said Liveris.

"Not to mention her ability to grow revenues and manage expenses and a lot of people.

"These sorts of qualities came through, as did her desire and passion.

"Getting an Olympics offer is really life-changing."

Queensland Premier Annastacia Palaszczuk described Hook’s arrival as a "very significant step on our path to 2032".

"Important behind-the-scenes work like the appointment of a chief executive will soon make way for other exciting announcements," said Palaszczuk in a report by ABC.

"This will be our golden age."
