Thanks Rob for such a quick reply.

Thats was my best guess but am unsure as it was just such a sudden issue. I guess its about time i had a mechanical issue in my 10 months of ownership haha.

With this over heating exercise i also found that the oil that i thought was coming from the gearbox that i was talking with you about earlier tonight was in actual fact coming from the purge tank over flow. Not sure if this has something to do with the over heating issue i have.  

 
Have you opened the bleed valve behind the spare wheel when filling the coolant?

Radiator cap is one thing, but also the plastic filler neck on the cooling system can weather and let air in, usually at the top of the first turn.

The way i gauged that it was about 2L lost was by how much i put back in before it over flowed.
 
you may have lost more than 2 liters, as it normally takes a long time to properly fill her up and bled. then u kept driving it with not enough coolant and air pockets in d system. ur lucky u werent driving in d freeway as it will not shut off untill ur head is cooked. i popped one of the cooling system hose once and over heated, shut d motor straight away lost most of the coolant. lucky caltex was round d corner, n lucky i have sum hose in d car that i used to temporarilly rigg her up. i filled and bled the system  with tap water for more than 4 hours on d side of hoddle street on a rainy night.  (emergency fill and bleed, just so i could safely drive the car home and perform a proper flush and bleed)  
blown head gasket is d least of ur problems, blown cooked head is d worst case scenario

No i didnt touch it, just filled it up and turned the engine on for it to suck it through and then refill again. My father and i didnt realise there was a bleed valve and that it needed to have the bleed valve open when filling her up. Just thought it was like filling up any other car with a self bleeding system.

At least this is experience i can now learn from. Mind you the damage was already done before i even realised there was an issue, im just happy it didnt get so hot that it could of siezed the engine. 
 
Thank you everyone for all the help, you all have helped increase the learning curve that much more. 
 
Ill post up the extent of damage once i find out

LOL its not that f**king hard! :)
Spent about an hour draining and refilling Josh's SW20 turbo yesterday, as long as you have the car up in the air at the back and you bleed the system correctly (i.e, radiator bleed, HC bleed and filler cap) then you will be fine!  Due to the sheer size of the system, burping it every few days for about 2 weeks afterwards is a good idea as it can get rid of the slightest bubble in the system that would get forced around by the water pump.
 
The worst thing you can do to them is stick cold water in an overheated engine... Then wonder why your car wont start LOL.
