My wife just bought the Sydney & Sydney North Entertainment Book, and when she registered her card it said that she was eligible for a free $50 Voucher to Use with Virgin Australia Holidays. I also noticed that the link was generic and managed to claim a $50 voucher for myself too. If you're not a member of Velocity Frequent Flyer it is free to join. Enjoy.
