The Chromecast came out in the US in July last year, but despite a recent expansion of markets it still isn't officially available in Australia. Looks like that might be about to change: Dick Smith is listing the Chromecast on its site.
The Dick Smith listing says the Chromecast will cost $49 and will ship on 28 May. That seems broadly in line with the US pricing of $US35, albeit a tad on the high side.
It seems likely that other retailers (and Google's own Play Store) will also offer the device around that date -- we'll keep you posted. There are lots of apps which support Chromecast, but if the Chromecast comes with a native ABC iView app, we'll be very happy.
Update: The listing seems to have been pulled -- but that might just indicate someone going live a little early, we suspect.
Thanks Beau for the tip!
