ABOUT
SOUTHWEST UNDERGROUND POWER

Southwest Underground Power is a specialist electrical infrastructure contractor delivering complex underground power, trenching, and boring projects across rural Western Australia. Operating as a division of SEC — Southwest Electrical & Communication — we bring together the heavy machinery, technical expertise, and field experience required to tackle the region's most challenging civil electrical works.

From long-distance underground cable runs through remote terrain to precision horizontal boring under tight-access sites, our crews are built for the jobs other contractors won't take on. We own and maintain our own fleet of trenchers, boring rigs, and cable-laying equipment, which means predictable costs, reliable timelines, and no reliance on third-party hire.

Our clients include rural property owners, agricultural operators, local government, and utility providers who need dependable underground power infrastructure installed safely and to specification. Every project is managed end-to-end by experienced supervisors who understand Western Australian ground conditions, compliance requirements, and the logistics of working in remote locations.

Southwest Underground Power is backed by Sykes Engineering Pty Ltd and operates from 23 Ramsay Terrace, Donnybrook WA 6239. One company, three specialist divisions — built to break ground and get it right.
