A proposed tightening of firearms laws will make the offensive use of low-velocity toy air guns a crime. If legislators agree to the planned changes, toy air gun owners will no longer be able to shoot at windows and property with near impunity. Currently, air gun owners can only be prosecuted if they wound someone or damage property, and a complaint is made. But under an amendment to the 1996 Firearms and Ammunition Amendment Ordinance, the reckless or negligent firing of an air gun under two joules 'to the annoyance or danger of the public' will become an offence punishable with a $500 fine or three months' imprisonment. The bill is awaiting its second reading in the Legislative Council. Police do not know how many toy air guns - those classified as having a muzzle capacity of under two joules - are in circulation, but they are widely available in shops and do not require a licence. Inspections are not carried out on retailers to check they are not selling more powerful air guns, classified as firearms under the law. Police Senior Superintendent Steve Robins said police did not test every toy air rifle but most retailers were 'very responsible'. 'If they want to import an air rifle that they think might be over two joules they ask us to test it. 'Obviously you are going to get rogue ones [retailers] and then we operate on the basis of complaints.'
