Woolworths booze branch is called BWS (Beer Wine Spirits), and you can buy specific discounted gift cards for it through your app. Once you have selected your tipple, scan your rewards extra code at the counter, buy your booze, pay for it with the discounted gift card and get double points.

Many have a specific bin in the home/garage put aside for collecting cans and bottles that attract a 10c return. When the bin is full take it to an electric return machine in town and slide them in. Get your voucher and it can then be used at a number of outlets on other shopping.

Note: If you are posting to the NT you will need to show ID to purchase alcohol. At time of writing digital cards are not accepted.
