Terri will be joined by Australian champion surfer Mick Fanning in the global ad campaign.
Could he be more Aussie?!
Celebrity chefs Kylie Kwong and Curtis Stone, will also have a role in the ads.
And did we mention comedian Adam Hills will be starring in them too?
Tourism Australia has had a huge number of successful advertising campaigns in the past, with Chris Hemsworth and Lara Bingle both starring in the ads.
Chris starred in Dundee: The Son Of A Legend in February 2018, which was a fictional sequel to Crocodile Dundee.
The elaborate commercial was aired during the Superbowl to much fanfare, with it even prompting talk of a potential sequel film.
