Dunbier & Mackay: Acquired by 2nd Summit Capital
Wednesday 4 November 2026
Braeside, Australia
The acquisition of Dunbier Marine and Mackay Trailer Products, two of Australia’s most iconic and trusted names in marine manufacturing, will unlock new opportunities for customers and dealers across Australia, while ensuring uninterrupted service, delivery and quality.
Dunbier was founded by Russell Dunbier in 1969, and custom boat trailers were added to the range with the acquisition of Mackay Multi Link in 2015. Dunbier and Mackay have manufactured hundreds of thousands of trailers for dealer networks and Russell Dunbier continued to work in the business until his passing in 2025.
The acquisition will expand strategic support to invest in new product development, manufacturing expertise and operational capability across Australia and New Zealand.
The existing senior management and operational team will remain in place, ensuring that support for dealers, customers and supply chain partners continues uninterrupted.
Managing Director Michelle Reid, who will retire following the acquisition, said that finding a partner who shared an appreciation for the deep industry expertise and brand heritage of both companies was critical.
"For our family, ensuring the future of Dunbier and Mackay remains strong, secure, and true to its values was our highest priority,” said Michelle Reid.
"I want to acknowledge my parents Russell and Kay Dunbier, whose vision and tireless work laid the foundation of this incredible business over 50 years ago, and Tracy and Matt Jackson for their dedication and immense contribution to making Dunbier and Mackay the successes that they are today.
"Passing the torch to Jonathan and the team at 2nd Summit Capital allows us to preserve that proud family legacy while ensuring the customers who have relied on us for decades will benefit from an expanded support network and a dedicated team of existing individuals who will carry the brands into the next decade.”
General Manager Andrew Murphy, who joined Dunbier in 2019, will continue the Dunbier legacy by assuming the role of Chief Executive Officer following Michelle Reid’s retirement. Andrew Murphy said his role was to ensure customers can expect the same service they have grown to know and love from Dunbier and Mackay.
"Importantly, our entire senior management and operational management team remains in place. Our dealers, customers, and supply chain partners can expect complete continuity in day-to-day operations, backed by the same dedicated team they have trusted for years,” said Andrew Murphy.
It has been a privilege to work alongside Russell, Kay, Michelle, Tracy and Matt over the past eight years. Their passion and focus on the business is extraordinary, matched only by their determination to succeed and focus on delivering the best outcomes for customers."
Founder of 2nd Summit Capital, Jonathan Cutting, said success would be measured by preserving the brand’s reputation for quality and reliability, while driving the next phase of growth.
"For over five decades, the Dunbier family has been building these brands into industry leaders known for quality, reliability, and continuous innovation,” said Jonathan Cutting.
“We are pleased to bring Dunbier and Mackay into 2nd Summit Capital’s growing portfolio of Australian specialist manufacturing businesses.
“Australian manufacturing has a storied past, and a strong future. 2nd Summit Capital is committed to protecting the legacy and investing the future of incredible Australian businesses,” concluded Jonathan Cutting.
