Battery life might be a stretch, but I have the Lenovo Yoga 2 Pro. Excellent laptop/tablet downside is battery will only last 6ish hours unless you put it on power saver, then it will last about 7-8 (8's a stretch) it's 3lbs too so it's likely one of the lightest 2-in-1s out there Since you're Australian I'm not sure if you can get this one, but it has an Intel 4th Gen i5 and has 7+ hour battery [url=http://www.bestbuy.com/site/ideapad-yoga-ultrabook-2-in-1-11-6-touch-screen-laptop-4gb-memory-128gb-solid-state-drive/1835037.p?id=1219065985762&skuId=1835037&st=computing-campaign-118727&cp=1&lp=2#tab=reviews]Lenovo Yoga 2 11.6"[/url]
