Our People
“When workplace issues are complex, clients don’t just need an answer. They need advice and judgement they can trust.”

Michael Brown
In memory
Michael Brown was a valued member of the Red Wagon team, a dear friend and colleague, and a deeply respected industrial relations practitioner.
He brought extraordinary knowledge, sharp judgement and practical wisdom to his work across IR strategy, enterprise bargaining, union negotiations and contract bid matters. Clients and colleagues trusted Michael for his steady hand, his deep experience and his ability to see both the high-stakes landscape and the nuance.
To many in the industrial relations profession, he was Brownie – funny, generous, direct, and always ready to share a lesson and a story.
Michael’s contribution to Red Wagon reflected the best of our practitioner-led approach: deep expertise, personal integrity and advice grounded in real-world experience.
We remember him with gratitude, affection and respect – and with a smile for the stories, the wisdom, the Carlton commentary and the fine vintage he would no doubt have preferred us to raise in his honour.
Rest in Peace
