Benzac BP gel is available in Australia. Most chemists stock it in 5% but to follow the regimen ask them to order in 2.5%.

I started the regimen using benzac but found that once you start ramping up the BP to the amount the regimen describes, the cost starts to mount up. Plus the Acne org BP is far superior to benzac. I would suggest that you start with Benzac, see if you're going to be able to stick with the regimen and if you are, bight the bullet and order Acne.org products.

Good luck!

I'm Australian and am using Benzac AC 2.5% for my benzoyl peroxide (can be found at any chemists, priceline, mychemistwarehouse).

For cleanser I'd definitely recommend Cetaphil! I use the one for oily skin but many love the gentle skin cleanser version. It receives really good reviews here and is nice and basic. You can get it at all chemists and supermarkets.

For moisturiser I use Dermalogica but Dan recommends the Cetaphil lotion as an alternative. You could also try Neutrogena oil-free moisturizers.

I had a harder time finding a glycolic acid product that wasn't $100 in some crazy serum concoction so I bought this: http://www.iherb.com/Neoteric-Cosmetics-Inc-Alpha-Hydrox-AHA-Souffle-1-6-oz-45-g/52333#p=1&oos=1&disc=0&lc=en-US&w=aha&rc=81&sr=null&ic=4 last night. It''s only $15ish and $8 postage with a couple of days shipping only. It's the cheapest I have found available, even with postage. Otherwise I have heard good things about Neostrata products from chemists and mychemistwarehouse http://www.chemistwarehouse.com.au/product.asp?id=36161&pname=NeoStrata+Ultra+Smoothing+Lotion+200mL

Pure Jojoba Oil can be found at health food stores and most chemists I use rosehip oil instead.

Neostrata with glycolic acid, they also have other products with glycolic which are slightly cheaper

The Simple skincare brand has a range of products that would probably be more than adequate replacements for The Regimen products. I'm currently using one of their moisturizers and I am so impressed with it. I'm in NZ btw so I know your pain. I also use the Benzac 2.5%, it's about $25-30 here but I imagine it's a little cheaper over there.
