We've all been whining about it since the dawn of time, and Apple has finally partially answered our calls. App store pricing has just been adjusted downwards for Australians, meaning apps that used to cost $1.19 in Australia now cost 99 cents — the same as the US.
The same change applies to the lower app pricing tiers: $2.49 apps are now $1.99, $3.99 are now $2.99. In the higher tiers, there's a 50 cent premium on the US price (so a $4.99 app in the US is $5.49 here — cheaper than it was, but not an outright match). Here's a more detailed explanation of the changes.
There's no change on the music or movies front, which presumably reflects the fact that Apple has different local deals with individual labels, but deals with developers on an international level. Nonetheless it's a welcome change for Aussies (other countries are actually seeing price rises, but our long-term currency strength seems to have paid off here.)
