Aussie Excavators began as determination to build a better future, and has evolved into a powerhouse in plant hire solutions and civil contracting — shaping roads and a reputation for excellence along the way.
In 1985, long before digital scheduling platforms or the noise of modern business, there was a small office, a telephone, a handful of committed owner-operators, and a young girl doing the books, taking the calls, and keeping the wheels turning.
Holding the fort by herself, Leanne Sullivan could be forgiven for laughing at the notion that the company she was running would grow into one of Queensland’s most respected names in civil contracting.
Leanne’s father was her silent partner in those early days, and she remains grateful for his business acumen, his wisdom, and the many lessons he passed on.
The initial years of working out of her parents’ backyard in the suburb of Chandler laid the foundation for the business that would evolve into Aussie Excavators Plant Hire.
Today, as the organisation celebrates its 40-year anniversary, its origin remains as much about grit and growth as it is about family and the power of sticking together.
Humble beginnings, big dreams
Most successful businesses start with a vision. This one started with a need, and the determination to fill it.
Aussie Excavators’ Civil Contracts Manager Peter Baldwin takes up the story.
“In the mid-80s, the earthmoving industry was a different landscape. Queensland was on the cusp of major development, yet the industry itself remained fragmented, reliant on personal networks and trust,” he said.
“It was in this environment that the Sullivan family saw an opportunity.
“With just five owner-operators and Leanne managing every aspect of administration, the business began to take shape.
“Jobs were booked manually, schedules updated with pens and correction tape, and relationships were built the old-fashioned way: by answering every call, solving every problem, and showing up for clients no matter what. Slowly, momentum grew.”
The true turning point came in 1993 when Leanne met her husband, Tony Sullivan. At the time, Tony was a butcher. But with a shared belief in building something meaningful together, he sold his shop and purchased a Bobcat and tipper.
“It was a bold decision — the moment the business began shifting from simply coordinating operators to building a fleet of its own,” Peter said.
“Over the following years, Leanne also worked closely with her siblings, collaborating and investing in various aspects of the business.
“Those early partnerships strengthened family ties and business acumen, and today, they continue to share business interests and work together in ways that reflect that foundation.”
Machine by machine, job by job, they invested back into the business. As demand increased, Tony’s role naturally evolved, encompassing operational oversight as the company grew more complex.
“It was never about titles — it was about doing what the business needed at each stage of its growth,” Peter said.
The business was boosted by the appointment of a dedicated General Manager, Ian Duthie.
The leadership role helped formalise operations, ensuring that systems, safety, and standards kept pace with expansion, allowing the Sullivans to focus on strategic growth while maintaining the family values at the heart of the business.
“This was the era that changed everything. Aussie Excavators Plant Hire began building not just a company, but a legacy,” Peter said.
Family matters
Like any family business, life and work were intertwined. The Sullivan household doubled as a command centre: paperwork on the dining table, phones ringing during dinner, schedules updated between school runs.
Their three daughters — Sheridan, Chloe, and Emma — grew up immersed in the rhythms of the company. From stopping at the office on the way home from hospital as newborns so Mum could do the wages, to taking up positions in the office during busy periods, they lived the business as much as their parents did.
Each contributed in different ways over the years, helping shape a company culture defined by loyalty, adaptability, and heart.
“This wasn’t just a business that supported a family. It was a family that supported a business,” Peter said.
Adapting to a growing state
As Brisbane and South-East Queensland expanded through the 1990s and 2000s, Aussie Excavators Plant Hire grew with it.
“Urban development boomed. Infrastructure demands accelerated. Developers needed reliability, consistency, and capacity — and the Sullivans ensured they could deliver exactly that,” Peter said.
“The fleet expanded strategically: excavators, dozers, graders, tippers, Posi-tracks, low loaders and beaver tail trucks — each addition allowed the business to take on more complex work.
“With growth came responsibility: safety systems, maintenance management, operator training, compliance requirements, and scheduling logistics that grew more intricate every year.
“Yet through every change, one thing remained constant: the company’s commitment to doing things properly — good operators, quality machines, honest communication, work delivered the right way.”
Weathering the tough years
No 40-year story survives without resilience. The company has weathered recessions, industry shifts, economic downturns, and the challenges inherent in running a fleet-based operation. There were years that required sacrifice and sheer determination.
During these tough periods, the Sullivans’ values shone strongest. They leaned on their people, strengthened their systems, tightened processes, and pushed through with the same determination that defined their beginnings.
Technology changed the landscape too, and the business embraced it. Paper logs and whiteboards were replaced with digital scheduling, fleet management systems, and modern compliance tools. Yet the heart of the business — the relationships — remained the same.
“Aussie Excavators knew they had to evolve not only to stay with the market, but also to be on the front foot and leading in areas of the industry,” Peter said.
Built on reputation
Across thousands of jobsites, the company earned a reputation for reliability. Clients knew that when they booked through Aussie Excavators Plant Hire, the machine would show up, the operator would be skilled, and the job would get done properly.
“This reputation wasn’t crafted through marketing, but earned over many years — in early mornings, muddy boots, tight deadlines, and clients who kept returning because trust matters in this industry more than anything else,” Peter said.
A legacy lives on
As the business celebrates its 40-year milestone, it stands on the strongest foundation in its history.
With the transition into broader civil contracting well underway, the company is positioned not just to continue, but to thrive.
“This story is about more than excavators and earthmoving. It is about a family choosing to build something lasting. It is about an unwavering commitment to doing things well,” Peter said.
“Forty years of showing up, growing, adapting, and believing in what’s possible. And with the next chapter unfolding, the Sullivan family’s legacy continues — stronger than ever.”
