iOS 7.1 is on its way, with Beta 5 seeding to developers recently. Included in the update looks to be a tweak to Siri to make her sound more Australian.
There aren't any official details about exactly how Siri will sound more Australian just yet, but we know that Apple has shipped the language tweaks to developers already.
Australia's not the only country getting a language tweak, however, UK English, Japanese and Mandarin Chinese are also up for tweaks.
