Big River Industries Ltd, a leader in the manufacture and distribution of timber and building products, has acquired the business and assets of John’s Building Supplies, one of Western Australia’s most established trade-focused building materials suppliers.

The acquisition strengthens Big River’s national trade network and expands its presence in the high-growth Western Australian construction market. John’s Building Supplies services builders, subcontractors and commercial customers across structural timber, engineered wood, cladding, lining and interior fitout categories.

Founded more than 40 years ago, the company has built a strong reputation for service, reliable supply and longstanding customer relationships. Its operations align closely with Big River’s strategy of growing scale in resilient trade-focused segments and increasing its presence in key regional markets.

Big River CEO John Lorente said the acquisition represents an important strategic milestone for the business.

“John’s Building Supplies is a high-quality Western Australian business with deep relationships and a long track record of supporting the trade,” Lorente said. “This acquisition broadens our presence in a key growth region and strengthens our offering across the structural timber, panels and building materials categories. We have great respect for the business John Lindsay and his family have built, and we look forward to welcoming the team into the Big River Group.”

John Lindsay, representing the owners of John’s Building Supplies, said joining Big River marks a natural next step for the company.

“Our family has always focused on providing trusted service, quality products and dependable supply to the WA trade market,” Lindsay said. “Big River shares those same values. Becoming part of Big River ensures our customers will continue to receive the personalised service they rely on, while benefiting from the scale, product range and national strength of a larger group.”

Existing customers and supplier partners will continue to be serviced without interruption, with both businesses working together to ensure a smooth transition. The existing management team will remain in place to support continuity for staff and customers.

Completion of the acquisition is expected on or around 15 December 2025, subject to customary conditions. John’s Building Supplies will continue to operate from its Western Australian site under the Big River network.

Western Australia remains one of Australia’s strongest construction markets, supported by ongoing population growth, infrastructure investment and a robust resources sector. The acquisition positions Big River to capture additional demand and further strengthen its service capabilities in the region.

Big River has been operating for more than 120 years and manages 24 sites across Australia and New Zealand, supporting the commercial, residential, civil and infrastructure sectors with an extensive range of timber, plywood, panels, formwork and building products.
