I know this is likely going to be better than "other options in Australia", and I respect their efforts for making this happen, but that's not my point. I was comparing "options in Australia" to "options in the rest of the world".
The same happens with a lot of different things, such as the cost of computer hardware/software, furniture/home appliances, cars, etc. Occasionally it's possible to work around it: I buy most of my gadgets from Amazon or other US/EU online retailers, and even with international shipping it's cheaper than buying locally. Unfortunately we often get hit hard on the larger, more expensive items that are impractical to import: IKEA furnitures cost 3x as much as in the US, cars 2x as much.
