Our Story
At the Jonah Group, we work with you at a personal level to understand the DNA of your organisation. We deliver sustainable results by providing solutions that will become deeply embedded and thrive throughout your organisation. Our intent is authentic and our story personal. It stems from our founders’ personal experiences.
Director Nada Wentzel was working in the crisis management team at Esso Australia when the Longford incident occurred in 1998. Two people died and seven were severely burnt. She knew the people affected and saw the effects on the people around them both at work and at home.
Less than six months later, both Nada and Robert were themselves involved in a horrific personal accident. Nada suffered burns to 35% of her body, requiring several skin graft operations and months of rehab. It took her months to learn to walk again and 10 years to have the confidence to wear skirts without opaque stockings.
Nada says, “Rob and I were both mechanical engineers at the time working in the oil, gas and mining industry. The incident involved camping; it wasn’t work-related. Logically, I can see how it could have been prevented, but when you’re exhausted, cold, hungry and distracted, nothing is logical. People have incidents because their brains are not always in logical mode. Safety is not rational. It is a complex weave of logic and emotion”
Nada remembers thinking, “How can two intelligent people, two mechanical engineers, not connect the dots?”

Our Values


Love what we do
We’re passionate and committed to making a difference and connecting people to the very essence of what it means to be human. We love what we do. We pour our hearts into helping people realise that the choices and decisions they make can save lives.

Take Ownership
We’re up to big things. Causing behavioural and mindset shifts requires muscle and resilience. It involves having the hard conversations, owning the results and delivering on our promises. It’s not always easy, but it is what our reputation is built on.

Authentic Partnership
Gone are the days when a single person holds all the answers. Collaboration and collective mastery are a key part of how we work with each other and our clients. It’s why we’re known for generating results that thrive well after we’ve left the room.

Respect Your Business
We value honesty, transparency and are super conscious of making sure you get absolute value for money. Our people are awesome. Each and everyone one of us acts as the owner of our business. We are accountable for actions and take pride in building strong and honest relationships. Sounds awesome? It is.
In The Community
The Jonah Group has a commitment to making a profound difference in our local and global community.
At a local level, we support initiatives through sponsorships, donations, and workshops & presentations to schools and business forums.
At a global level, The Jonah Group have been active supporters and proud investors in The Hunger Project since 2003 where Rob sits on the NSW Advisory Board.

About The Hunger Project
We know it’s possible for hunger to end, and that our generation has the power to end it once and for all. In our experience, people who live in poverty are not the problem – they are the solution. We don’t see a billion mouths to feed, we see a billion human beings who are enterprising and resilient.
The work, therefore, is to unlock their capacity, creativity and leadership so they can end their own hunger.
The Hunger Project empowers women and men living in rural villages in Africa, India, Bangladesh and Latin America to end their own hunger. They reach more than 18 million people who are transforming themselves, their families and their communities, and are bringing about the end of hunger by 2030. www.thp.org.

Future Dreamers
Nada is also active in the development and empowerment of young girls through the Future Dreamers and Kind-Hearted Rebels Programs designed to stimulate curiosity and provide confidence and growth for young girls.
Future Dreamers is a girl’s club in the heart of Byron Bay. It aims to empower young women to dare to dream, activate their creativity and achieve business success. Learn More
