We pride ourselves on being an equal opportunity employer, where gender and indigenous diversity continue to be a focus to ensure everyone always feel comfortable at the workplace. We engage, encourage, and hold our people to account to live and breathe our core values.
MACA was originally founded in Western Australia in 2002 as Mining and Civil Australia. The company has now grown from a specialised mining and civil contracting business to a large Australian and International contracting partner of choice. Through a number strategic acquisitions, MACA has grown to holistic, end-to-end Mining, Infrastructure and Construction sector partner. In 2022 MACA was acquired by Thiess Group Holdings Pty Ltd and proudly became a subsidiary of the Thiess Group.
The driving force behind MACA’s success for the past 20 years has been our people. We put the safety of our people first because we care. By engaging with our clients, subcontractors and employees, we drive this commitment and the shared responsibility for our safety, health and the environment.
At the core of our business, is our drive towards our social responsibility and the communities in which we operate. We show leadership and take responsibility for the community and acknowledge that our choices can have a positive impact and leave a legacy.
Our “Can Do” approach is our competitive advantage which sets us apart from other contractors. We have a solution-focused outlook and develop collaborative relationships with our clients, partnering together to achieve a project outcome.
