As engineers, we’re innovators at heart. We believe places and spaces can be made better by thinking outside the box.

With the right team working with you, even your most complex idea can be realised. 

We meet the challenges, seek out the possibilities and expand the vision to bring your idea to life in its finest form.

Our Ethos

At JN, we embrace the ethos of Responsive Engineering.

Being responsive means being ready to go, ready to listen and ready to think deeply about what it is our clients really need.

Being responsive also means being ready to deliver, with the right people, best processes, and state-of-art technologies all in one place.

Our values are at the heart of our culture and our brand.

The way we work with clients and each other is driven by our values: things we recognise as fundamental to our great work and great service.

Building and Maintaining Trusting Relationships

Being transparent and keeping the lines of communication open. Always working ethically, with high moral values.

Adding Extra Value Through Service

Going beyond the norm of expectations to surprise and delight clients, colleagues and industry associates.

Striving for Excellence

Aiming to produce outstanding quality work; surpassing ordinary expectations.

Thinking Ahead

Thinking about what clients are going to need or want before they ask for it. Future-proofing projects.


Working together towards a common goal. Collaborative effort.

Owning It

Taking ownership and responsibility for delivering on commitments. Being accountable.





Australian Owned



The JN story began over 50 years ago

Trevor Punnett established T.C. Punnett & Associates out of his small home office in Sydney’s South. After 20 years, the company evolved into Jones Nicholson, a multi-disciplinary engineering firm with a reputation for practicality and cost-effectiveness.

Fast forward another 30 years and we’ve grown exponentially in capability and experience. We work with public and private sector clients in a variety of industries and have expanded from our base in Sydney into various regional centres in NSW and most recently Queensland.

Today JN operates with a team of 90 staff working out of nine offices in NSW and Queensland.
