Eight projects across government, infrastructure, energy, and conservation — spanning spatial strategy, corridor modelling, ecological assessment, platform development, and network optimisation.
These case studies span the past five years of geospatial and ecological consulting work, delivered across government, infrastructure, and conservation sectors. A number were completed in a technical lead capacity before BioGeo was established — all reflect the rigour, methodology, and hands-on senior delivery that defines how BioGeo works today.
Indicative least-cost route between a major gas pipeline offtake and an industrial development area, to support early-stage cost estimation. Built a multi-criteria cost surface across a broad corridor from five weighted themes (environment, terrain, hydrology, tenure, and regional planning) plus non-weighted hard, prohibitive, and strong-avoidance tiers, run through Distance Accumulation and Optimal Path in ArcGIS Pro Spatial Analyst. Rather than commit to a single weighting prematurely, trialled two scenarios — ecology-led and directness-led — presented side by side for comparison.
Principal consultant and sole report author. Designed and implemented a full MCDA framework across a large state development area to identify developable land opportunities for industrial development. Four weighted sub-models (physical, technical, ecological, and planning) were applied across the study area. The Locate Regions algorithm was run across 93 configurations varying background model, area threshold, and region count — demonstrating that the priority locations are consistent across all variants and reflect genuine underlying spatial patterns, not modelling artefacts.
Geospatial and modelling lead within a multidisciplinary engineering team, providing the spatial analytical framework underpinning all corridor evaluation for proposed pipeline infrastructure linking to a regional export port. Designed the centralised web GIS platform for stakeholder data access, led MCDA expert committee inputs, standardised 150+ constraint datasets across four domains (environmental, engineering, safety, and project suitability), and applied both least-cost path analysis and Circuitscape circuit theory — delivering insights single-path analysis cannot. Co-authored the comparative technical report assessing conceptual versus optimised routes.
Technical lead for multi-species ecological assessment supporting highway bypass route selection in an ecologically sensitive region. Applied MaxEnt ecological niche modelling at continental scale for all 17 threatened species, refined at regional scale through weighted MCDA integrating vegetation, regional ecosystems, bioclimatic variables, and disturbance factors. Developed ecological resistance surfaces and applied Circuitscape to identify corridor bottlenecks and constrained linkages not captured by single-path analysis — producing a composite ecological cost comparison across all alternative bypass alignments.
Designed, built, and managed a bespoke web GIS platform with integrated mobile data capture, replacing a paper-based field process across a national gas pipeline network spanning thousands of kilometres — including remote areas with no connectivity. Delivered offline data capture (auto-syncing on reconnection), automated alerts for significant species detections, live field team GPS tracking, automated species identification logging with photographs, KPI dashboards across pipeline sections and date ranges, and automated compliance reporting outputs. Handled all requirements gathering, architecture, development, and deployment.
Three separate engagements spanning six years to optimise the logistical deployment of sampling and servicing teams — with dual objectives of cost reduction and mitigating driving-related safety risk identified as a significant operational concern. Applied advanced network analysis algorithms solving the travelling salesman problem, modelling real operational constraints including maximum field time, workday duration, hub locations, and team configurations. Updated and refined across three engagements as the network and resource configurations evolved.
Habitat suitability and landscape connectivity assessment for koala and greater glider (both listed as threatened under state and Commonwealth legislation) to inform a mine expansion and associated works. Developed species-specific sub-models integrating vegetation type, regional ecosystem mapping, water proximity, and occurrence records, combined using weighted overlay. Applied an integrated analytical framework — least-cost modelling, Linkage Mapper network analysis, and Circuitscape circuit theory — to identify corridor probability surfaces, pinch points, alternative pathways, and priority restoration zones for each species.
Habitat suitability and connectivity model for the threatened brush-tailed rock-wallaby, commissioned to support active conservation planning. Developed sub-models incorporating vegetation type and condition, terrain roughness (proxy for predator refugia), aspect, slope, proximity to water, and species occurrence records — combined via weighted overlay. Converted the suitability surface to an ecological resistance layer and applied least-cost corridor modelling to identify core habitat patches, stepping-stone areas, primary corridors, barriers, and pinch points. Translated outputs into practical conservation recommendations.
First in a three-project sequence of commissioned work on a state development area. Comprehensively assessed the capacity of an existing multi-user infrastructure corridor spanning two disconnected sections. Mapped infrastructure layout, assessed access rights and tenure, quantified available capacity for new infrastructure, and identified three confirmed pinch points at key infrastructure crossing points. Built a geospatial portal for stakeholder data access and engaged infrastructure providers to validate operational datasets.
A selection of cartographic outputs — geology maps, MaxEnt model visualisations, corridor maps, suitability models, terrain analysis, and web mapping applications.
