Thanks for the pics.
I wonder if she is related to Joost Van Der Westhuizen, the rugby player from south africe.
Even though we can search in English, it's generally quite difficult to get info of a competitor from RSA.
Because the information is simply sparse. It's sad for me.
Fortunately, about her, there is an article.

There isn't any coment on the referred rugby player. I also found her facebook page.
facebook.com/Alex-Maud-van-der-Westhuizen-BikiniFitness-model-309547192533632
But I couldn't find his name there neither.
And her/his surname is a common Afrikaans surname according to the page about the surname in Wiki.
So it's less probable she's a directly related family member of the rugby player.
