OUR

STORY

Founded in 2018 by Corey Firth, CJ Tech Services Pty Ltd brings big-industry mechanical expertise to southwest Victoria.

Growing up farming, Corey turned a lifelong passion for machinery into a professional trade, completing his apprenticeship in Melbourne before gaining extensive experience across remote mining, tunneling, civil construction, and marine industries.

Guided by the motto—"If it has wheels or an engine, we can repair it"—he launched the business in Melbourne’s western suburbs to serve major local corporations, before eventually returning home to bring elite, hands-on mobile plant servicing back to his regional roots.
