The sustainability industry has lost a supporter with the death of Master Builder NSW’s executive director Brian Seidler over a week ago.
Brian spoke to us ahead of his taking part in our Let’s Hack Housing event last year and revealed deep care for the traditions of quality building and the power of collaborative work to meld seemingly intractable paths. We were fans. Big fans.
Following are some of the tributes that flowed for an exemplary figure of the building industry.
A lifetime of dedication to the industry
The Master Builders Association said Brian dedicated over 40 years to the association, including 25 years as executive director of MBA NSW. He was 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.
From Former NSW Building Commissioner David Chandler
Brian was a special mate to the construction industry. He was a family man first and an industry advocate always.
I valued his advice and support as NSW took on turning around the industry’s former race to the bottom.
Brian recently commented on how pleasing it was to see quality builders now being able to stand out.
There are too many touchpoints to call out. Perhaps the most distressing and enduring period of industrial lawlessness, the impact on MBA members and the consequential impact on construction cost, the damage to the attractiveness to construction’s next-gen constructors caused him considerable distress.
He always pushed through with a positive spirit.
Brian was always the consummate gentleman and respected advisor to all sides of politics.
At every level, Brian Seidler will be sorely missed.

His leadership and vision helped shape MATES in Construction’s mission to support those in need, ensuring that suicide prevention and mental health remain a priority in our industry.Beyond his professional achievements, Brian was known for his kindness, integrity, dry wit, and unwavering commitment to making a difference. He touched the lives of many and will be profoundly missed.
Our heartfelt condolences go to Brian’s family—his wife Donna and children Amelia, Marcus, and Mila—during this difficult time.
His legacy will continue to inspire us, as will his contributions to MATES and the broader industry.
