Collieries’ Staff and Officials Association

Collieries’ Staff and Officials Association Trade union representing staff, supervisors, deputies, OCEs, technical and administrative workers in the Black Coal Mining Industry since 1921.

Our History

In 2001 Australian Collieries’ Staff Association (ACSA) amalgamated with The Association of Professional Engineers, Scientists & Managers, Australia (APESMA), now known as Professionals Australia. This formed the Collieries’ Staff and Officials Association (CSOA). The two associations joined together to further strengthen their collective voice and resources to best represent professionals across the country. ACSA has been fighting for the rights of workers in the coal mining industry since 1944. It was responsible for such wins as severance pay in 1973 and redundancy pay in 1983. ACSA, and now CSOA, has continued to secure pay rises and safe conditions for all who work at the coalface. In 2016 the Collieries’ Staff and Officials Association won a landmark case against Centennial Coal over their policy of age-discrimination that saw workers over 60 not receiving redundancy pay. All Centennial Coal workers now have full redundancy pay locked in their agreements.

Do you remember in 2022 when CSOA members took Peabody to the Federal Court for unpaid sick leave on redundancy and won? ✊

The FWO has today announced that the remediation process that followed that CSOA win has resulted in Peabody entering into an Enforceable Undertaking after backpaying mineworkers nearly $5 million! 🤯

None of this would have been possible without the hard work of CSOA members who fought and won for their entitlements. Today we say thank you to those members and congratulations to all who have received their fair share for their hard work.

Every worker deserves to come home safely at the end of their shift.

Our recent CSOA Delegate Training in Mudgee brought together union delegates from across the region for a valuable day of learning, collaboration, and skill building.

From strengthening workplace representation to building confidence in advocating for members, CSOA delegates shared experiences, developed practical knowledge, and reinforced the importance of standing together to create safer, fairer workplaces.

A huge thank you to everyone who attended and contributed to the discussions. The passion and commitment shown by our delegates is what makes our union stronger every day.

Together, we're building stronger delegates, stronger workplaces, and a stronger union.

⏰It's time for BMA to come to the bargaining table⏰

This week, the Fair Work Commission refused BMA's application to appeal the Majority Support Determination which gave CSOA members at Hay Point Coal Terminal the right to bargain for a first-ever agreement.

After more than 18 months of our members standing together and fighting for their rights, it's time BMA showed them the respect they deserve and met with CSOA members at the bargaining table.

💪 CSOA Goonyella members are standing together in their fight to protect and improve their conditions in an enterprise agreement. 💪

Their application to require BHP to commence bargaining with Supervisors, Coordinators and Technical/Autonomous Specialists was recently heard by the Fair Work Commission. A big thank you to workplace reps Derek and Shaun who made the trip to Brisbane to represent CSOA Goonyella members at the hearing!
