Challenging Minds Pty Ltd is an NDIS registered provider of Therapeutic and Positive Behaviour Supports. At present, Challenging Minds operates throughout the Northern Territory but is looking at future expansion in other regional areas across Australia.

We provide high-quality services and can be best described as “boutique”, specialising in disability, mental health, substance use, dual disability, early onset dementia and dual diagnosis. We are also looking to expand into training and early intervention. This expansion marks an exciting time for Challenging Minds, but more importantly, for participants, their families and loved ones. Our commitment is to increase the capacity of individuals, services, and communities to thrive, thus improving the quality of life of people we are proud to support.

For all of us at Challenging Minds, honesty, integrity, reliability, and sincerity are of most importance. We take pride in following through with our commitments while focusing on people’s strengths, needs and aspirations.

The team works to challenge you, ourselves and others to think positively, differently and honestly. We know that change can be difficult, but with the right support and guidance, change can become less challenging and more rewarding.

We encourage people we support as well as their significant others to think a little differently about what’s possible.

Challenging Minds is an incorporated company with the Australian Securities and Investments Commission (ASIC).
