These articles take the wrong perspective - it's not that Australia is much more expensive in tech matters, it's that the US is much more cheap. I don't know where the recent Australia-specific articles are coming from, but it's been like this since as long as I can remember - that the US is much more cheap than any other country I'm familiar with for tech stuff, including Australia, but also almost every other country.
For example in Europe, the same suite mentioned in the article costs USD 4552.14, or $200 more expensive even than Australia.
