Understanding Firearms and Weapons Offences in New South Wales: Examples, Penalties, and Available Defences

Law enforcement and the courts take firearms and weapons offences in New South Wales (NSW) very seriously. Governed by the Firearms Act 1996 and the Weapons Prohibition Act 1998, offences range from unauthorised possession or use to trafficking firearms or weapons. 

Firearms Offences

Unauthorised Possession or Use

It is an offence to possess or use a firearm without a valid licence or permit. The severity of the offence and associated penalties vary depending on the type of firearm. For instance, unauthorised possession of a pistol carries a maximum penalty of 14 years imprisonment.

Possession of Unregistered Firearms

Firearms must be registered under the Firearms Act. Possessing an unregistered firearm can lead to a maximum penalty of 14 years imprisonment.

Safekeeping Offences

Firearm owners are required to store their firearms safely. Failing to adhere to the prescribed storage requirements can result in a maximum penalty of 12 months imprisonment and/or a fine of 50 penalty units.

Use of Firearm Under the Influence

Using a firearm under the influence of alcohol or drugs is a severe offence, with a maximum penalty of 2 years imprisonment and/or 50 penalty units.

Trafficking Firearms

Illegally selling, buying, or transferring firearms is considered trafficking. This offence is punishable by a maximum of 20 years imprisonment if involving five or more firearms.

Weapons Offences

Possession of Prohibited Weapons

The possession, use, buying, or selling of prohibited weapons without a permit is an offence under the Weapons Prohibition Act 1998. The list of prohibited weapons includes items such as flick knives, laser pointers, and knuckle dusters. The maximum penalty is 14 years imprisonment.

Possessing dangerous items intending to commit an indictable offence carries a maximum penalty of 2 years imprisonment.

The law provides for several defences to firearms and weapons offences. These include:

Duress and Necessity

These defences applied when the defendant was compelled to commit the offence due to threats of harm or in an emergency where breaking the law was the only viable option.

Lawful Excuse

This defence can be used if the defendant can prove they had a legitimate reason for possessing or using the firearm or weapon.

Lack of Knowledge

A defendant may argue they did not know they had the weapon or firearm. However, this defence requires substantial proof to be successful.

Mental Illness

This defence applies if the defendant can demonstrate they were suffering from a significant mental illness when the offence was committed.

Firearms and weapons offences in NSW carry significant penalties, reflecting the seriousness with which these offences are treated. Individuals must understand the law surrounding these offences and the potential defences available.
