Can I Get An SDI From A Happy Ending. I

Can I get an SDI from a happy ending. I was getting a Asian massage and the girl offered a little extra. We were both nude. How were no sex took place. She was masterbsteing me and I was touching her vagina. No genital contact was made. I'm not sure if she touched herself. And I didn't touch myself with the same hand as I touched her. What's my risk. I lived in Australia and I'm Australian.
