Parkway Corporate Secures Site for Queensland Brine Management Complex

Parkway Corporate (ASX: PWN) has secured a 10-hectare site for its planned Queensland Brine Management Complex (QBMC), a landmark project to transform coal seam gas waste brine into valuable green chemicals.

The site, which Parkway obtained through a binding option-to-lease agreement, will host the company’s integrated brine processing and electrochemical facilities, providing a long-term solution to one of the energy industry’s most persistent environmental challenges.

Chief executive officer Mr Bahay Ozcakmak said the acquisition marks a critical milestone toward establishing Parkway as a developer of strategic brine infrastructure.

Strategic Location in Heart of Gas Industry

The site lies within Queensland’s Western Downs region at the centre of the state’s coal seam gas (CSG) industry and adjacent to major infrastructure including high-voltage power lines, substations, and a planned renewable energy precinct.

It also sits near key regional roads and the Kenya Chinchilla water pipeline, offering options for reusing treated water in agriculture.

The location allows for efficient integration of the QBMC’s two main components — the brine management and electrochemical processing units — into one highly synergistic industrial complex.

Parkway subsidiary Queensland Brine Solutions will develop the QBMC to process up to half of all brine produced by Queensland’s CSG industry, including legacy waste currently stored in evaporation ponds, using Parkway’s proprietary processes to convert waste brine into commercial products such as industrial salts and green chemicals.

The facility will also have potential to expand its capacity to treat waste brine from emerging gas projects in the Taroom Trough basin and other regions.

Progress on Approvals and Partnerships

Development approvals and environmental assessments are in motion, with pre-lodgement meetings yielding positive feedback from regulators.

Parkway believes the QBMC could become Australia’s first purpose-built facility offering permanent, compliant liquid waste disposal for the gas industry once approved, and is also advancing partnership discussions with upstream CSG producers, downstream chemical manufacturers, and infrastructure providers.

Mr Ozcakmak said securing the site represents the culmination of more than two years of planning and site evaluation.

“Parkway is now another step closer to becoming a developer of highly strategic brine processing infrastructure that underpins the long-term sustainability of Queensland’s $100 billion gas industry,” he said.

Parkway expects project execution could begin as early as mid-2026, subject to approvals and funding, positioning the QBMC as a cornerstone asset in the company’s transition to large-scale commercial operations.
