The 21-year-old was finally sent packing by Elle Macpherson and her fellow judges after landing in the bottom two for the third consecutive week following her 'Do It Like A Dude' photoshoot.
Commenting on Tas's continued presence at the end of the call-out order, Macpherson said: "It's always for the same reason, it's because we see so much potential in you and it just isn't translating in your photographs."
Speaking to Digital Spy about her departure, Tas admitted: "I kind of knew my time was running out, so I kind of was expecting it.
"I think maybe [Tyson Beckford] felt I did alright, but all of them together didn't think so."
Tas also agreed with Julien MacDonald's comments that she was a "little girl in the body of a model", explaining that she felt "scared" throughout the Top Model experience.
"I definitely was totally inexperienced," she confessed. "I entered the competition not really expecting to get on it, and then I did, so it was kind of like, 'Woah, I'm scared'.
"They had all the cameras and stuff, it was all a bit overwhelming... [I was] unprepared and intimidated.
"I think I'm learning a bit more how to work in front of the camera... I learnt that you need to believe in yourself and black out what other people say, because if you let things get to you you just crumble."
Tas went on to describe dressing up as a man for this week's challenge as "exciting" and played down the tension arising between Roxanne and Maddie.
"Living in a house with the same people, looking at the same faces every day, it's tricky," she noted. "So you just kind of argue about things, but you learn to get over it and find things to argue about next week."
On Beckford's rant about Roxanne's demeanour during the call-out, she added: "It was all kind of weird. Everyone's jaw kind of dropped.
"He said some other stuff to me. You gotta just learn to deal with it and try not to take it personally."
