Buy discount Woolworths wish cards when they are on sale! CashRewards can be a good place to do it!

FLYBUYS
Start an account at Velocity, and transfer FlyBuys miles there with a 15% bonus. At a later date, I could transfer them to KrisFlyer with a similar bonus!

From time to time, FlyBuys offers to double your point earning capability for a limited period of time if you link your Velocity account.
According to Keith at Point Hacks, 2.5 Flybuy Points = 1 Etihad Mile. FlyBuys can be transferred to the Etihad program. On top of that, there is a 500 mile bonus for signing up with Etihad!

ALI BABA, AUSTRALIA
Sign up for an Ali Baba rewards card and you will get enough points for a free kebab. They will also give you a free kebab on your birthday!

Card Cash: Website here.
Recommended by One Mile at a Time. Even though it is an American site, it may be possible for purchase etickets from abroad. The last time I checked, there were Hotels.com vouchers available for a 7% discount. What's more, you can pay with Bitcoin!

COMMONWEALTH BANK REWARDS: website here.
Download the bank's app, which can be used to store your loyalty cards.

MENULOG: .
Once I move into the Halfway House, I will be hitting this service. It seems possible to earn 1 Flybuys point with $1 purchased on Menulog, but it is better to use Cash Rewards as a gateway instead.

NANDO'S: .
Buy a Westfield gift card at Coles and then claim FlyBuys and Amex points (2% discount). Then dine at Nando's and accrue Nando's points!. Perhaps I could even buy a Coles card at Woolworths and accrue some Qantas points in the process!

WOOLWORTHS: .
My Woolworths Rewards account set up!

With Amazon coming, discounts might become more audacious. Even without discounts, there are savings to be had from ordering online, in bulk. I found an ad online promising 1500 bonus points for joining their rewards program. In general, 2000 points equals 10 Woolworths dollars. So, only 500 points to go, before I get a discount! They can also be transferred to the Qantas points system at a rate of 870 Qantas points for every 10 Woolworths dollars.
As of June 2017, Woolworths is running an offer on Groupon where you can get $5 off the final $30 of an online order of more than $120. On top of that, the groceries will be delivered to your home for free. I am not sure if this means $150 of groceries for $125, or $120 for $95. If the former is true, it represents a discount of 17%!
