Our Identity
Imaging the subsurface to optimise resource allocation to minimise risk.
A proudly Australian-owned and operated geophysical consultancy specialising in non-invasive subsurface investigations.
Our methods provide precise and actionable insights, empowering businesses and councils to make informed decisions about subsurface conditions — without the cost or disruption of invasive drilling.
We employ a wide array of geophysical methods with a strategic approach to provide accurate, cost-effective, and environmentally friendly solutions tailored to your specific needs across Tasmania at the most competitive prices.

Our Methodology
Phased Approach to
Site Characterisation
A systematic four-phase framework that moves from broad reconnaissance to quantitative analysis — delivering maximum insight with minimum site disruption.
01
Desk Study
Targeting Strategy
- Review of existing records, maps and reports
- Local and structural geology characterisation
- Identification of target zones, contact zones and faults
- Scoping of appropriate geophysical methods
02
Site Reconnaissance
Survey Planning
- Survey design and profile orientation
- GPS coordinate planning — start, stop and line spacing
- Confirmation of client objectives and investigation area
- Logistics, access and safety assessment
03
Field Survey
Geophysical Investigation
- First-pass data acquisition across all survey profiles
- Multi-method deployment — EM, ERI, GPR, MAG, seismic
- Anomaly detection, unit mapping and structural identification
- On-site QC and real-time data review
04
Reporting
Processing & Analysis
- Inversion, modelling and data integration
- Anomaly prioritisation and interpretation
- Drilling targets, remediation or design recommendations
- Comprehensive geophysical survey report
