I went into my local DSE this morning to purchase the Vita/Killzone bundle posted by theearth a few days ago, only to discover they're selling the console unbundled for $169. Strangely not advertised online, but this was the price it scanned through as.
Nothing I can find suggests that the unit is locked to Vodafone (although a Vodafone sim is included). Furthermore, the game Wipeout 2048 is included when you make your first Vodafone recharge (minimum $10, http://www.vodafone.com.au/personal/wireless-internet/mobile…), so not a bad deal if you aren't on PS+ (it's currently US$13.49 on US psn or free with PS+).
Dangerously tempting
