I currently see only two options for boric acid down under.
The first one, and the only one using an official pool product, but quite pricey is Bioguard's Optimiser:
bioguard.com.au
Note that the Optimiser sold by Bioguard in Australia is 100% boric acid, which is different to the Optimizer (note the z) in the US, which is a mixture of different borates.
The other option is to go through these guys:
www.boricacid.net.au
Be aware, this is sold as an insecticide, but is 100% boric acid (sold as "technical grade" with 99.5% purity) without deliberate additives, as far as I know. I can't really recommend that, up to you if you want to give this a shot.
[Edit]
They sell their boric acid as a "versatile household product", with the main application as an insecticide, but they also advertise it to be used as a hand washing detergent and a washing powder additive.
[/Edit]
I have used both. Both are fine powders, rather than granules that are easier to add to a pool, and I personally don't see a point in paying the adder for a dedicated pool product, but you have to decide for yourself.
There may be options in farm supply shops.
