Just put together a couple of random flights I saw on Helloworld today, some of which seem to be pretty good deals. Dates vary, generally around Oct/Nov 16.
Note: Conditions Apply Prices displayed are ‘from' pricing, includes all taxes and fees, except payment card fees which may be payable in addition, rates vary. As far as I could see, 2% for Visa/Mastercard, up to 3.6% for AMEX, not sure if there's a way around it but if there is, ozbargainers will know about it.
