Great Southern Land Group · Est. 2017
Precision in
every dimension.
Surveying, mine surveying, cartography and machine robotics — one group, delivering across Australia and the Asia-Pacific.
Divisions
Four disciplines. One standard.
Each division is specialised — all are connected by a single purpose: accurate, practical outcomes for your project.
GSL Survey
Engineering set-out, control networks, geodesy, scanning, UAV and monitoring — the founding discipline of the group.
Enter division
GSL Mining
Underground and open cut mine surveyors across Australia and the Asia-Pacific — contributing from day one.
Enter division
GSL Cartography
Maps, plans, 3D models and automated reporting — spatial data your whole team can actually use.
Enter division
GSL Machine Robotics
The GSL sentinel and GSL relay — survey-grade monitoring and communications, engineered in-house.
Enter divisionGSL sentinel
Continuous highwall monitoring. Anywhere on site.
Trailer-mounted RIEGL laser scanning, running 24/7 and entirely off-grid. Sub-centimetre change detection on every scan, instant SMS and email alerts, and results your whole team can see — available on fully managed, flexible hire.
The Group
From a single survey crew to a four-discipline group.
GSL was founded in 2017 as a surveying consultancy built on control networks, precise set-out and geodetic work. That discipline remains the foundation — today the group spans survey, mining, cartography and machine robotics, sharing equipment, systems and people across Australia and the Asia-Pacific.
When our field teams hit a gap that off-the-shelf tools can't close, we engineer the answer ourselves. That's how the sentinel was born.
