i just traded my 5 speed manual ba xr8, with a little work done for a ba xr8 ute auto with a s**t tin of work plus 1500 from him... the utes body is ruff but it runs fine, this morning i started it, normally you have to rev it i little to get it going which i think might be the oil type... maybe to cold, but im in darwin!!!! any ideas, and this morning i did it and it didnt start at all just died and wouldnt turn over...

Does it just make a clicking sound? My car used to do this, get a battery charger or a battery jolt and try it. The contacts in the starter solenoid wear out/corrode and won't start without a little extra voltage. You could also tap the starter motor/solenoid while someone tries to start the car.
Hope this helps

yeah cheers man that did help, it was the battery even though its fresh battery

Cool, hopefully in your case it is the battery and not the starter motor. Soooo much easier to replace!
