The parts you picked are quite extreme. A 3930k and 32GB of RAM is veeery overkill.
You'v over-budgeted a bit.
I don't know of any stores in Adelaide and I bet postage would be horrendous to post from the stores I do know. So here's a link to a search engine which will find the cheapest online price to the component within the state. Just select South Australia and type the component name in.

CPU: i7-3770k
Mobo: AsRock Z77 Extreme4
PSU: Unsure of availability in SA, just get one from Corsair, Silverstone or Seasonic at 750W. Make sure its modular and 80+ Bronze or better. This will leave you room to Crosssfire/SLI.
HDD: Seagate Barracuda 7200RPM 64MB cache. You decide the capacity as you'l be best to judge that.
SSD: Crucial M4 128GB - if you want to play it safe, these are very reliable drives.
OCZ Vertex4 - if your willing to gamble for faster speeds. These are pretty good so far but haven't been out long enough to tell for sure if its reliable yet. Iv had no issues on mine so far.
RAM: G.Skill Ripjaws or Corsair Vengeance 16GB 1600Mhz at 1.5v. No difference other than aesthetics.
Optical Drive: Just check any local stores if they have $20 SATA DVD drives, the specs on these don't really matter given how little their used.
Case: This is largely personal preference, so I'l link to some cases which fit your budget. All of these cases will serve you well. I can vouch for the HAF-X.

GPU: ASUS or Gigabyte GTX670. You could get two of these running in SLI on that motherboard, but you wont see any tangible diffrence unless your gaming on multiple monitors. So don't bother running dual cards unless you get a triple monitor setup. This card will overclock past stock GTX680 performance, so saved you $100 or so.
CPU Cooler: Corsair H100. Very nice looking water loop and while it doesn't perform as well some air heatsinks (I think its the Noctua one), it should lead to a tidier looking build to look at through the side of your case. It also lets you pick RAM without worrying about clearance. This thing will let you overclock very nicely as well.
OS: Windows 7 Home Premium 64Bit OEM.
Sorry I cant give you a definite price since I don't know where your getting the components, but I'd estimate around $2200 - $2500
