$100 off Webjet Hotel Bookings over $600 Using AMEX (Direct and Bank Issued)

As always with webjet, best to check some competitors first as they don't always have the best prices. With $100 off they should be competitive.

Fairly handy for doing that: http://www.hotelscombined.com/

Appears to be for any time, so long as it's booked by the 17th (last point of the Ts and Cs)
