Tamaryn will be rooming with Miss Thailand, Ning Sophida, for the duration of the pageant.
The beauty queen has also been quick to make new friends, taking a selfie with Miss Australia.
Reflecting on her journey leading up to the Miss Universe pageant, Tamaryn wrote: "The moment I've been looking forward to for so long, to wear the South African name across my chest, and in my heart."
"I feel your love and support all the way from Bangkok," she added.
