Canadian air gun supply
I'm sorry to say but airsoft is illegal in Australia.
Nerf gun
No
The best airsoft gun you could get for $150 would probably be an Aftermath gun, but you could get a JG M4 or M16 for under $150

The one you can afford
If you are just starting airsoft i would highly recommend an aeg, (airsoft electric gun) but if you are pro and experienced, a trained camouflaged sniper is the best, an invisible predator. However it does depend on the user of the gun. If you are asking performance wise then g&g makes the best airsoft guns on the market. (currently in the US)
I say twin ozez are the best cheap airsoft guns
dont get that gun walmart has the best beginer guns
Definitely Nerf.
it depends on what cheap is to you
