We knew local stock of Valve's Steam Controller and Steam Link was incoming, though if you were expecting some fanfare about their availability, you're going to be disappointed. EB Games has quietly put the devices up for sale, though the pricing leaves a lot to be desired.
The sad, though I suppose unsurprising, thing is that it's still much cheaper to buy both the controller and Link from Amazon. Even when you factor in shipping, they individually come to around $58 Australian (with the Link's more expensive postage bringing the price up).
To be fair, there's no stock for the $US19.99 Link, so if you were to try and get it now, it'd be closer to EB's price.
Of course, the biggest benefit of being able to purchase locally is that you don't have to wait. But if you can be even mildly patient...
