Theres and airsoft site on the net where u can order overseas. I'm just wondering if there's a certain age you have to be to order into australia or any paperwork, etc you have to have to order them into the country. The site says nothing except and when I emailed them, they just told me they had shipped to Australia successfully before, but said nothing about age, etc.

That's the site, just incase anyone's wondering. Any info helps, thanks.

They don't care who you are. They are in another country. I know in the UK they have to be under 3 ft/lbs of energy (300 fps with most pellets). Even if it is illegal the only place you will run into trouble is your country's customs service. If it is illegal they may grab it, but that rarely happens.
