Heifer creek cutting
Thiess Bros completes the 104-foot-deep Heifer Creek Road Cutting between Gatton and Warwick - the deepest in Australia at the time. Demonstrating their ingenuity, they decide it is more efficient to carve a cutting, rather than following the specifications for a tunnel. A Brisbane newspaper dubs them “the men who eat rocks and stones”.
Thiess Bros wins its first job in NSW - sinking the Young Australia tank for New Occidental Gold Mine. This project marks Thiess’ first foray away from roadworks and building site preparation.
