the IT industry in australia is really picking up, there was a big crash, where all the big companies moved overseas from australia a few years ago, but they say 2005 is the year for it to skyrocket again.
Its like anywhere though if you got a degree and some experiance you shouldnt have any trouble finding a job, especially seeing as australia's un employment is at record lows
It really depends on where you move though, Im not sure about Perth, but in nsw, it is a very big place, and house prices really depend on how close you are to the CBD, whilest you might find cheap housing in northen nsw or qld, you chance of getting a programmign job is slim to none.
The other factor deciding prices (at least in sydney) is ocean/water views, australians love the beach, and love a house overlooking water (or a landmark like the bridge)
If you want a job in Programmign definitly go for Melb or Sydney.

As for bringing your fto over, There are 3 ways to register an imported car for australian roads.
1) 15 years old (or more) you can pretty much register it and drive, with min fuss or costs.
2) Compliance the car to australian standards, you are looking at an overal total of around 2-3k gbp (including shipping) this is an estimate.
The problem is at the moment no one will complaince and FTO, and also the car must be fully stock.
3) this is proberbly the best method for you, if you have lived in a country for more then 12 months, you can bring the car with you. there is minimal complaince and costs for registration. your main costs will be shipping the car. before you transport the car, look up the exact ruling, because i think there is paper work before you even send the car.
Here is some good information you should read

If you have all your stock parts for you car you are proeberbly best to return your car to stock, sell it and bring your parts here (depending on weight and things) and buy a car already imported, you are looking at around 7,016.93 GBP for a 95-96 model.
