Here's my referral link for this fantastic card - it is a must in your wallet if you eat out often as it gives 3 points per dollar on all restaurant/cafe spend (particularly great if you pay the bill for the group and have everyone give you cash or transfer their share!) - Restaurants/Cafe's also generally have good Amex acceptance.
Also great for travelers as it's 3 points per dollar on QF spend and 2 points per dollar on all other airlines, cruise lines, accommodation, travel agencies plus all foreign spend (including online)! On top of this you get a free Qantas Domestic flight each year after your first QF spend - which means you can actually get great value out of the $450 annual fee!
With the 80000 extra Qantas points on offer when you apply by 31 May 2016 - it is unquestionably a great card to have if you like travelling and eating out, which I imagine is most people here!
