If it's the same girl, http://rosevillerose.com.au/?page_id=25 mentions her name as "Tania(African)" and she's rostered for Saturday. I also found her on a private escort site (same photo) for $500/hr via a Google reverse image search, but unfortunately there's no photo of her currently on the Roseville Rose site.
Where in St Leonards did she work? Could be worth checking out....
