Vale Brian Seidler

We are deeply saddened by the passing of Brian Seidler, a respected leader in the Australian building and construction industry. Brian passed away on March 1, 2025, after a brief illness. Our thoughts are with his wife, Donna, and children, Amelia, Mila, and Marcus, as they navigate this difficult time.

Brian dedicated over 40 years to the Master Builders Association, including 25 years as Executive Director of MBA NSW. A tireless advocate, he worked to strengthen the industry, improve standards, and support members. His leadership was crucial during economic shifts, industrial challenges, and the COVID-19 pandemic, where he played an instrumental role in keeping construction sites open, ensuring thousands of workers could continue to provide for their families.

Brian was more than a leader, he was a mentor, a strategist, and a trusted voice within the industry. He played a key role in industrial relations reforms, helping shape modern employment frameworks that benefited both businesses and workers. His involvement in establishing CBUS Super ensured financial security for countless construction professionals. He was also a key advocate for the introduction of a Building Commissioner to enforce quality and accountability, helping to drive lasting improvements in the sector.

A cousin of renowned architect Harry Seidler, Brian had a lifelong appreciation for design and construction. Growing up in a modernist home influenced his deep passion for architecture, leading him to restore mid-century homes with meticulous care. His appreciation for well-crafted structures extended beyond his personal projects, as he worked tirelessly to uphold the highest standards in the building industry.

Beyond his professional contributions, Brian was an advocate for mental health and wellbeing in the construction industry. He supported Mates in Construction, an organisation dedicated to suicide prevention among workers, and championed greater mental health awareness. Additionally, he actively promoted opportunities for women in construction, recognising the importance of diversity and inclusion in shaping a stronger industry.

Brian’s influence reached far and wide, extending across industry boards, advisory committees, and training programs. He was committed to equipping future generations of builders and tradespeople with the tools and knowledge they needed to succeed. His ability to bring together employers, unions, and government officials to find common ground made him a respected and unifying figure in the industry.

The construction sector has lost a dedicated leader, but Brian’s legacy lives on in the policies he helped shape, the mentorship he provided, and the industry improvements he fought for. His passion, integrity, and commitment to a stronger and fairer construction sector will be remembered for years to come.

May Brian rest in peace.
