As far as I know any airgun in Australia needs to have a police license, while in the UK the law is different - any airgun having a muzzle energy of less than 12 ft/lbs (for example 0.177 calibre firing an 8 grain pellet at around 800 feet per second, or 0.22 calibre firing a 16 grain pellet at around 550 feet per second) can be owned by anyone over 18 without a license. Anything capable of going over this energy limit however is considered legally to be a firearm and is subject to similar licensing restrictions to powder burners.

With a long enough barrel and big enough chamber, 50 psi will put a marble through half an inch of ply easily.
