Thread: Air Rifle Kills Teenager

Section 48 of the Arms Act 1983

Discharging firearm, airgun, pistol, or restricted weapon in or near dwellinghouse or public place
Every person commits an offence and is liable on summary conviction to imprisonment for a term not exceeding 3 months or to a fine not exceeding $3,000 or to both who, without reasonable cause, discharges a firearm, airgun, pistol, or restricted weapon in or near—
(a)a dwellinghouse; or
(b)a public place,—
so as to endanger property or to endanger, annoy, or frighten any person.

So pretty much it's fine as long as you're being careful and not pissing the neighbours off.
