What Westside Group does

Westside Group is a privately held Australian multi-discipline building services contractor headquartered in Royal Park, Adelaide, founded in 1998. The group operates four wholly-owned subsidiaries — Westside Mechanical Contracting, Westside Services (SA), Westside Plumbing, and Poly Pipe Fabrications — delivering mechanical services, commercial plumbing, 24/7 HVAC service and facility management, and polyethylene pipeline fabrication for healthcare, government, defence, commercial, and resources customers across South Australia and the Northern Territory.

The group's technical stack combines in-house BIM/Revit 3D modelling and drafting capability with a simPRO-based service management system integrated to field tablets for real-time job tracking. Poly Pipe Fabrications operates Australian Standards-licensed butt, electrofusion, and extrusion welding for industrial pipeline work. The group also distributes higher-margin technology products including the in-house RackDoor rear door heat exchanger (launched 2025, up to 70kW cooling), Aura Air smart air purification, and Steril-Aire UVC germicidal solutions.

Westside generates revenue primarily through two channels: major project mechanical and plumbing installations (tender-based, project values up to ~AUD 20 million, including government and defence work where the group holds DTPI category 1 prequalification above AUD 2.5 million) and recurring service and maintenance contracts with 300+ clients. Annual group turnover is approximately AUD 40 million at ~120+ staff plus 20-30 specialist subcontractors, with no external equity investment and a privately held ownership structure.
