Experience the difference of working with Australia's leading surveying professionals. Precision Delivered since 2012.
Pioneering drone surveying in Australia with advanced LiDAR and photogrammetry capabilities for rapid, accurate data collection across any terrain.
Access challenging or dangerous sites safely with our certified drone pilots and advanced UAV fleet, delivering data where traditional methods can't reach.
State-of-the-art drone LiDAR, high-resolution cameras, and real-time processing delivering detailed topographic maps, 3D models, and volumetric analysis.
HR Surveyors provides professional drone surveying services across Australia with 70+ licensed surveyors and CASA-certified UAV operations. Unlike pure-drone operators, we integrate aerial data collection with traditional surveying expertise, delivering survey-grade accuracy for construction monitoring, mining stockpile surveys, infrastructure mapping, and volumetric calculations. Our national coverage includes Melbourne, Geelong, Brisbane, Gold Coast, Perth, and Adelaide offices.
Advanced drone LiDAR technology providing vegetation penetration and high-accuracy elevation data for terrain analysis, stockpile volumetric surveys, and mining applications. Our survey-grade LiDAR delivers precise point clouds and digital terrain models where traditional photogrammetry cannot penetrate vegetation canopy.
High-resolution aerial photography processed into detailed orthomosaics, 3D terrain models, and topographic surveys. Perfect for construction progress monitoring, site documentation, earthworks quantification, and visual project communication with millimetre accuracy when combined with ground control.
Specialized drone surveys for mining and construction stockpile volume calculations. Rapid data collection delivers accurate volume measurements, pit progression monitoring, and reconciliation surveys, integrated with our traditional surveying for verified results.
Unlike standalone drone operators, HR Surveyors combines UAV capabilities with 12+ years of licensed surveying expertise. Our CASA-certified pilots work alongside professional surveyors to deliver data that meets strict engineering and construction accuracy requirements.

CASA certified operations (ReOC 5661), licensed surveyors, ISO 9001 quality systems
With RTK/PPK correction and properly placed ground control points, drone photogrammetry typically achieves horizontal accuracy of ±20–50 mm and vertical accuracy of ±30–50 mm — sufficient for construction monitoring, earthworks quantification, and topographic mapping. Drone LiDAR achieves similar or better accuracies and works in vegetated areas. For structural set-out and construction control that requires ±5–10 mm accuracy, traditional total station methods remain the appropriate choice. We often combine both methods for optimal results.
Yes. Our UAV operations are conducted under a CASA-issued ReOC (Remotely Piloted Aircraft Operator Certificate), meaning all commercial drone flights are fully regulated and insured. Our pilots are experienced in operating within controlled airspace, near infrastructure corridors, and on complex construction sites.
Photogrammetry uses overlapping aerial photos to generate 3D models and is cost-effective for open terrain. LiDAR uses laser pulses that penetrate vegetation gaps to capture the actual ground surface, making it essential for sites with trees, scrub, or rough terrain. Neither is universally "better" — we select the appropriate method based on your site conditions, required accuracy, and budget. For many projects, combining both delivers the best outcome.
