Response time and recognition accuracy has sky rocketed for me since installing 5.0.1. Siri now loves Australians too.

For me Aussie Accent is a corrupt version of British accent. Siri shouldn't have too many problems with your Aussie accent if it works totally fine with my Brit/Indian accent. Worst part is I use US Siri. Actually I am totally surprised as to how it works so well.
Do you have that low mumbling/grumbling voice for Siri to not recognize you? But good to know it has been taken care off!!
