FAQ’s on Firearm & Weapon Offence Law in Australia

Is it legal to own a firearm in Australia?

Yes, but it is heavily regulated. In Australia, you must have a valid firearms licence and a genuine reason for owning a firearm, such as hunting, sport shooting, or professional use. All firearms must be registered, and strict storage and transportation laws apply. Owning a firearm without a licence is a serious criminal offence.

What is the Firearms Act 1996 (NSW)?

The Firearms Act 1996 (NSW) is legislation introduced after the Port Arthur massacre to tighten gun laws across New South Wales. It regulates the possession, use, manufacture, and supply of firearms. The Act sets out licensing requirements, firearm classifications, safe storage obligations, and severe penalties for unauthorised possession or use.

What are prohibited weapons under NSW law?

Prohibited weapons include certain firearms, items like flick knives, knuckle dusters, and other dangerous weapons deemed illegal to possess, carry, or use without special authorisation.

The Weapons Prohibition Act 1998 (NSW) governs prohibited weapons and imposes severe penalties for unauthorised possession or use.

What happens if I’m caught with an unlicensed firearm?

Possessing an unlicensed firearm is a serious criminal offence in NSW and can lead to significant penalties, including imprisonment. Depending on the firearm’s type and circumstances, charges may carry mandatory minimum sentences. Legal advice is crucial if you’ve been charged with such an offence.

Can I go to jail for possessing an illegal firearm or weapon?

Yes. Penalties for illegal firearm or prohibited weapon possession in NSW are severe and may include substantial fines and prison sentences. The seriousness of the penalty depends on factors like the type of weapon, the circumstances of possession, and whether the offence is a repeat occurrence.

Do I need a licence to carry replica or imitation firearms?

Generally, yes. Even replica or imitation firearms can be classified as prohibited weapons under NSW law, depending on their appearance and functionality.

Carrying or possessing such items without proper authorisation can lead to criminal charges. Always seek legal advice if you’re unsure whether your item is regulated.

What should I do if I’ve been charged with a firearms or weapons offence?

Seek legal advice immediately. Firearms and prohibited weapons offences carry serious legal consequences in NSW. A specialist firearms lawyer can explain your rights, assess the evidence, and develop a strong defence strategy. It’s important not to speak to police without legal representation and to attend all scheduled court appearances.
