I would recommend a Acer Aspire 5738PZG. It has a blu-ray a pretty bad processor and a decent graphics card but the price is fairly low considering it sells for 800ish in Australia. If blu-ray isn't that important and since your willing to buy a 1800 AUD for a computer 800 isn't a bad deal.
It is a lot better then the Toshiba one you showed and comes with 3d glasses. I know a lot of games don't support it but it would be nice to have.
Well if your not interested in 3d go for the recent discounted one since 1300 AUD for something as good as that 1800 AUD one is a good idea and having a i7 processor and better graphics card is always a plus when dealing with the less expensive laptop.
You should probably wait since lapyking sometimes comes out with prices for laptops with unbeatable prices and some other stores might do better. i7 is better but in some cases for certain programs people post better results FPS wise with i5 and pretty much the same specs but I doubt you care.
