Have you got a Sportsbet.com.au account?I have had someone ask me if I can refer them, but I don't want to as non- Aussies have a 5x WR on winnings from the RAF freebie, which is a pain in the arse. Aussies just get it treated as a normal SNR, as far as i know.
If you're interested in refering them and splitting your RAF 50:50 with them let me know and I'll put them in contact with you.
