Our social impact →

“I have had regular involvement with Frank Mitchell’s businesses for over 5 years and during that time have seen their genuine and ongoing commitment to Indigenous training, apprenticeships and employment, providing culturally proper backing for workers to realise their potential and achieve their goals. The Baldja Joint Venture’s commitment to worker wellbeing, upskilling and training is evidenced by their commitment of 10% of annual profit to a fund for this purpose, an initiative I have not come across in similar sized or larger Indigenous businesses. Furthermore, the number of Indigenous apprenticeships generated since Baldja’s inception in 2020 has been outstanding, to the best of my knowledge, unmatched by any other Indigenous joint venture.”

Acknowledgement of Country

We acknowledge the spiritual and cultural custodians of Whadjuk Nyungar boodjar, on whose land our office resides within proximity to the kwobidak Ma’tagarup, Derbarl Yerrigan. Furthermore, we acknowledge the traditional custodians of all lands throughout Australia, and the Indigenous peoples beyond our shores.

We pay respects to Elders, past, present, and emerging, for they hold the culture, stories, and dreams of the Aboriginal and Torres Strait Islander peoples. We recognise and respect the wisdom of the ancestors and Elders, their ways of knowing and doing, and their continued relationship with their land and waterways.

We also recognise the importance of Aboriginal and Torres Strait Islander young people, who are our future and our hope.

Finally, we acknowledge and respect all non-Indigenous Australians who share our vision for a fuller expression of Australia’s nationhood as we empower our First Peoples.
