What RSGx does

RSGx is an Australian mechanical and electrical (M&E) construction and engineering contractor headquartered in Rydalmere, NSW, operating across transport infrastructure, mining, oil and gas, renewables, transmission and distribution, water, data centres, and battery energy storage. The company delivers a full project lifecycle — front-end engineering and advisory, construction, commissioning and completions, and ongoing maintenance and operations — for clients including Fortescue, BHP Nickel West, Inpex Ichthys LNG, Brisbane City Council, and the South Australian Government.

Its core technical capabilities centre on high voltage electrical systems (33kV, 66kV and 220kV substations, overhead transmission lines, and underground cable networks), tunnel M&E integration (electrical, ITS, PA, lighting, and mechanical systems for road and rail tunnels), and emerging energy-transition infrastructure such as Australia's first Liebherr electric excavator charging installation at Fortescue's Solomon Hub and owner's-engineer representation for a 150MW/150MWh BESS at Hazelwood. Allied Power operates as a wholly-owned sub-brand providing specialised powerline EPC, and the recently acquired HISG adds health, safety and sustainability consulting.

Commercially, RSGx operates a project-based enterprise services model. Revenue is generated through professional services (engineering, commissioning, maintenance) and project construction contracts, supplemented by equipment hire through RSG Assets Pty Ltd. Engagement is direct with asset owners, councils, and tier-1 contractors across offices in Sydney, Perth (Burswood), Melbourne (Oakleigh), Brisbane Airport, Cooma, Adelaide, and Port Hedland. Pricing is not publicly disclosed; contracts are project-quoted with payment terms of 20 days from invoice approval. RSGx is a privately held proprietary limited company with no disclosed external investors and pursues growth via organic project wins and bolt-on acquisitions.
