Swart says competing in the show has been a blessing and revealed she has stayed friends with the other celebrities since the show finished filming.
"Dad taught me from day dot that if you're going to do something, do it well. Do it with everything you've got, or don't do it at all.
"This stuck with me throughout my athletic days, my university life, my corporate life and now in my business."
As the game progresses, Swart says she uses strategy — and hints that it puts a target on her back.
"It's quite funny to watch because you really feel like you're playing a huge adult-size game of chess."
There's a shock exit from the show this week with one contestant getting injured during a challenge.
"All I can say about that is a very strong player — and someone who could have taken out Celebrity Treasure Island — heads home before their time. But, not without putting up one last fight in a very difficult challenge."
In another twist, the three tribes are reduced to two this week.
"Let's be honest, the teams were slightly unfairly placed, but hey, that makes for a little more fun and entertainment," Swart says. "The switch-up obviously did come with a few challenges. I had to really scope out the lay of the land, sniff out alliances and decide who I thought would be best to partner up with."
