I have an ANZ Visa card and get 1 point for each $1 spent ,it depends where you shop because you can get bonus points from partners.
The gifts cards are Bunnings ,Kmart ,Coles and others and range fron $20 up.
I think others credit cards have similar schemes but you have pay a card fee as long as you put most of your spending on the card and pay of on or before the due date you made money from your credit card.
You need to check how many points against what you would spend to see if its worth while.
