what is SiSu?


"Extraordinary determination, courage and resoluteness in the face of extreme adversity. An action mindset which enables individuals to reach beyond their present limitations, take action against all odds and transform barriers into frontiers"


why SiSu Life?

We have experienced professional team sport. So, from first hand experience, we bring high performance coaching methods, formats and attitude to professional coaching into our programs.

We understand the value of "extras" or the "1 percenters" to achieving your best performance.

We have seen what outstanding preparation for practice sessions and for competition looks like and we have tweaked it to suit our programming.

We create efficient and effective session plans because we know the formats that maximise impact and minimise "BS".

Our reviews and feedback enhance the learning experience for long lasting behavioural change.

We have felt the pressure of professional sporting competition and know how to deal with it, and to make it work in your favour.

our services


As a leader you will be guided through a "season" of learning. We will show you how to effectively develop each of your team members as individuals and provide the right environment for them to excel.

You will get the chance to self-assess, clarify your communication, solidify your code or philosophy, improve your resilience, and ensure your vision is crystal clear.

We then coach you through the process of engaging with your team to ensure the mental skills and mindset skills required for consistent success are developed in them.

elite sport methodology

We have experienced elite sport environments and have experienced success and failure in them. From this experience we have taken the most effective methods to create successful individuals and teams and provided them all within our coaching programs.

We are not scientists or academics; we are coaches who have felt the palpable self-belief in a change room before a Grand Final victory. We have encountered the soul searching process of analysis following a shattering loss.


Throughout the Teams Program "season" we work with the leaders to help them effectively coach each team member as an individual with the overarching philosophy of creating a group that is greater than the sum of its parts.

We facilitate the stripping back of the team purpose, its methods of communication, its culture, its resilience, and its vision, and then help reconstruct it to a point where it creates consistent success.

We validate our improvements through evidence-based reporting so the development is tangible.

our clients




"I can not thank Dwayne and Kelly enough for their help and guidance. In my journey with them (exam preparation), strategies were tailored to my particular needs. Extensive research and consideration were put into a bold approach which was right for me. This included continuous evaluation of their own mentorship and tweaking as circumstances changed.

Dwayne and Kelly went above and beyond what would be expected of life coaching to see me succeed. They are sincere people who truly care with a never give up attitude. I cannot recommend them enough and am very grateful to have met them both."
