Indigenous business Tulli Resources has been awarded a $16 million contract from BHP Nickel West, the biggest contract it has ever awarded a Traditional Owner or First Nations business.

The Leonora company secured the record contract from the resources giant to provide its state-of-the-art, heavy mobile equipment hire and maintenance services at BHP's Camelot Pit project at Nickel West during the next 14 months.

Tulli personnel will work alongside on-site production and maintenance teams, who will provide training to build capability to perform key activities such as field leadership, work management processes for maintenance and following BOS routines during the execution of the contract.

BHP recently announced a new $1.5 billion spending target with Traditional Owners and First Nations businesses across Australia by 2027.

Tulli Resources is directed by Warwick Tullock, a Yamatji man from the Northern Goldfields and Midwest areas of WA, his wife Marisa Tullock, a Yamatji woman, and Shawn Tilley, who runs Paramount Earthmoving in partnership with the First Nations business.

Mr Tullock, a Yamatji man from the Northern Goldfields and Midwest areas of WA, identified opportunities three years ago to build a business with support from BHP Nickel West and other stakeholders existing on his families' Native Title areas, while still maintaining his profession as a teacher in the Leonara community.

"The opportunities were there, and so far our company set-up has allowed me to be heavily involved, but still teach, whilst Shawn handles much of the day-to-day operations," the father of four said.

"We had to put a lot groundwork in to land this contract but BHP were instrumental in providing constant support, be it through the procurement team, or the foundational meetings.

"That hasn't stopped now we have the contract; the transparency and the openness has been really good.

"BHP is a big company with a lot of safety standards and processes ... and is guiding us through all those processes, which helps us implement them within our business as we work together."

Mr Tullock said the record contract would likely lead to him taking a more prominent role leading Tulli over the next 14 months and beyond.

"We would like to create a big enough footprint within me and my wife's Native Title areas to generate employment and training opportunities for other native title holders," he said.
