Nash Mackey is a leading Australian Breakthrough Coach and speaker who specialises in helping high performers break through mental and emotional barriers, develop the perspectives and habits that build deep resilience and be at their best when it matters most.

His unique coaching approach brings together cutting-edge modalities in human behaviour, emotional processing, breathwork, nervous system regulation, subconscious mind transformation and high performance, creating a deeply integrated approach to human change and optimisation.

From enlisting as a Combat Medic at just 17, to navigating his youngest daughter’s open-heart surgery and later enduring the devastating loss of two siblings to suicide, Nash has been shaped by experiences that demanded resilience at the deepest level. In the wake of that loss, he went on to set a Guinness World Record, transforming profound personal pain into a mission to help others rise beyond adversity.

For the past decade, Nash has supported entrepreneurs, executives, athletes, CEOs and leaders around the world. His approach is not simply about pushing harder. It is about developing the inner capacity to remain grounded under pressure, move through adversity, expand what is possible and lead from a place of greater strength, awareness and purpose.

At the heart of Nash’s work is the belief that some of life’s greatest challenges can become the catalyst for our greatest growth and contribution.

And despite the many experiences, challenges and achievements that have shaped his life, Nash says his greatest achievement is the 17-year relationship he shares with his wife, Cassy, and the life they have built together with their three children.
