Hi Rob, I am from Melbourne too.
Depending on where you are, check the phone book for your nearest GNC store. They sell the best Whey Protein Powder--Designer, and their protein bars. They also have Atkins Advantage bars, Atkins Shake Mix, Pancake mix, muffin mix and a couple of other Atkins products.
I am about to order Empower Foods FibreX low carb cereal from Great Earth Discount Shop in the city as well as their Chocolate Rush muffin mix. The ingredients are very very clean and are gluten free as well.
If you are near Bentleigh there is a shop called USA foods and you can get Bakers unsweetened chocolate and Jell-O Chocolate and Vanilla instant pudding mix.
I tend to eat very clean--with the exception of GNC bake mix a couple of times a week with my pumpkin muffins and pancakes. About 20g carbs a day and 90g protein a day.
But...
if you are missing Snickers (my old weakness) I now make up once a month a copy of Reece's Peanut Butter Cups. I will only give you half the recipe as they are VERY addictive
2tbl chopped nuts, 1/4 cup butter, 15oz Darrell Lea Splenda chocolate, unless you have 1/2 square of Bakers unsweetened, 2tbl Splenda (1tbl if using DL choc), 3tsp cream and 1/8 cup Sanitarium Peanut Butter.
Melt butter, chocolate and Splenda in microwave SLOWLY. Stir in cream and PB. Put about 6 mini cupcakes in a mini muffin tin and evenly divide chopped nuts in bottom of each. Then pour choc mix evenly between papers. Freeze until firm. Must store in freezer, but boy they are sooooo good. 10g usable carbs and 10g protein.
