Same as this deal here which has expired (but slightly more expensive due to lower Aussie Dollar value): https://www.ozbargain.com.au/node/269146
Note that I'm still waiting for my order from that deal to arrive (it's almost been 2 months…), so I still can't comment on it personally, but judging by the specs, it's better than most of the power banks on OzBargain by far. And at 50% off, it's one of the best priced ones too. You may be able to shave a little more off the price by using the app.
Just don't expect it before Christmas…
