Similar to carrying a Swiss Army Knife, the legality of carrying a Leatherman or any multitool in Australia depends on the specific laws and regulations of the state or territory you're in, as well as the circumstances of its use. In many cases, carrying a multitool for legitimate purposes such as camping, DIY projects, or outdoor activities is generally allowed.

However, there are often restrictions on carrying such tools in public places or if there is intent to use them as weapons. It's essential to familiarize yourself with the laws regarding knife possession and carry in your area to ensure compliance. If you're uncertain, consulting local law enforcement or legal professionals for clarification is advisable.
