Looks pretty good for the price. 5" 1080p AMOLED screen and 13MP f1.8 Camera are probably the highlights. Apart from the design which personally I think looks amazing. Also it has "Hugely Power Enormously Efficiency" according to the website, and who doesn't want that?
No 4G will suit Optus 3G.

This looks really nice on paper. I hope chinese manufacturers manage to overcome the stigma associated with their products.
