Terrex Seismic is Australia’s leading onshore seismic surveyor with a 70% market share and a decades long history supporting Australia’s oil and gas, mineral exploration, and government geoscience research industries.
In April 2017, Allegro acquired a majority interest in Terrex Seismic as the seventh investment in Allegro Fund II, partnering with Terrex’s founder and Executive Director Steve Tobin to recapitalise the business. Under Allegro’s ownership, Terrex underwent a major transformation. Key initiatives included a full corporatisation, a significant investment in operational efficiency that improved margins by double digit percentages, and a successful strategy to lead the consolidation of the Australian seismic industry via bolt-on M&A.
In August 2025, Allegro sold the business to SAExploration.
