In 2004, Bree Amer made Big Brother history.
She was the first housemate to re-enter the house when, hours after her eviction, it was discovered the votes were miscalculated. She eventually went on to be the season's runner-up to winner Trevor Butler.
Bree's time on Big Brother opened up lots of opportunities for her, and she forged a successful TV career through hosting spin-offs Big Brother Friday Night Live and Friday Night Games.
After stints in front of the camera, Bree transitioned into a behind-the-scenes role as a producer on some of Australia's biggest reality TV shows.
Here is exactly what Bree's life has been like since her very first roller-coaster TV appearance.
In 2005, Australians would tune into Big Brother Friday Night Live each week.
Lucky for host Bree Amer, a doctor from Wollongong was among the viewers, and he noticed something unusual about her neck.
On Monday, Bree told the Daily Mail about how the doctor spent almost a year trying to get in contact with her, including by spending almost $400 calling through to Mike Goldman's Up Late show's competition line, to urge her to get a lump in her neck checked out.
"When I turned my head on the [Friday Night Live] panel, a lump protruded out of my neck - I had an inch and a half tumour that I never noticed," Bree told the publication.
