General, Medical & Health Electrical Solutions



GMH Electrical opened in 2016 as a small local business operated independently by the Director, Greg Hamill. With his background in the medical and heavy commercial sectors, Greg employed his technical skills and experience to grow GMH Electrical into one of the leading general and specialised electrical contracting companies in Cairns. Having since tripled in size, GMH pride ourselves on having an intelligent and unified team working together to provide the best service we can.

We aim to offer complete electrical solutions that cater to the diverse electrical marketplace in order to create sustainable and enduring business relationships. We prioritise training and skill development for our employees to continually expand our scope of works and strive for excellence in the electrical and trade industry.

Our continued growth and success is due to our core business values:

    Greg originally worked within the domestic construction and industrial electrical sector to develop his extensive skill set. He gained a vast range of experience with commercial communication and electrical systems in the time he spent working within a live prison redevelopment, in charge of perimeter lighting, security systems and liaising directly with the design engineers. After this project was completed Greg was offered a Leading Hand position for the electrical and communications company completing SP1 & SP2 for Cairns Hospital. As the SP2 project was coming to an end, Greg began fostering the idea of starting his own company to attend to the demand for specialist electrical contractors in the region. He opened GMH Electrical Contracting in 2016 and continues to advance GMH as one of Cairns leading specialised electrical companies.

    Dale brings to his role as Leading Hand an extensive amount of experience working in the domestic and commercial electrical industry. Beginning with industrial switchboard construction, Dale quickly advanced his career as an apprentice working at Cairns Hospital where he assisted with the installation of the mains to D Block and updating the emergency department electrical systems. From here he worked in Townsville on large commercial projects like the Stockland Shopping Centre and other multi-story offices and apartment buildings. Dale then worked in domestic and commercial electrical for a further four years in Cairns and Newcastle before settling down in Cairns as Leading Hand at GMH. Dale’s experience makes him an invaluable team member and our go-to man for our large developmental projects.
