TL;DR: A drone inspection survey in Perth uses a CASA-licensed UAV with high-resolution and zoom optics to inspect stacks, conveyors, headframes, wharf cranes and tailings embankments without scaffold or rope access. From a Perth base, Industrial Spatial Solutions covers the Kwinana Industrial Area, the Henderson marine-defence precinct, and FIFO assets across the Pilbara and Goldfields — cutting inspection windows from days to hours and removing people from height.
Key takeaways
- A drone inspection survey Perth operators commission typically covers Kwinana refinery stacks, Cockburn Cement kilns, Henderson shipyard cranes and FIFO mine assets, cutting inspection time 60-80% and eliminating the highest-risk working-at-height tasks under the WA Work Health and Safety (General) Regulations 2022.
- ISS captures imagery at 1-3 mm/pixel ground sampling distance (GSD) on close-range work, resolving hairline cracks, weld-toe defects and coating breakdown to the level expected of a hands-on inspection under AS 4100 and AS 3788.
- The work is regulated by CASA under CASR Part 101; ISS flies under a Remote Operator Certificate (ReOC) with licensed RePL pilots, registered aircraft and aviation-endorsed public liability cover.
- Perth's coastal humidity and salt-laden Fremantle Doctor sea breeze accelerate corrosion on Kwinana and Henderson steelwork, making repeatable, georeferenced visual inspection a condition-monitoring tool rather than a one-off.
- Single-asset inspections cost roughly $2,000-$6,000 versus $30,000+ for an equivalent rope-access stack campaign, with the payback usually realised on the first flight.
Drone inspection survey in Perth and Western Australia
Perth is the corporate and logistical hub of Australia's resources sector, but it is also a genuine industrial city in its own right — and the assets that need inspecting do not sit in head-office boardrooms. They sit on Cockburn Sound at the Kwinana Industrial Area, at the Australian Marine Complex in Henderson, on the wharves of Fremantle Inner and Outer Harbours, and at hundreds of FIFO mine sites that mobilise through Perth Airport every week.
What these assets share is access difficulty. A 60-metre alumina calciner stack at Kwinana, a kilometres-long conveyor gantry feeding a Cockburn Sound berth, a portal crane at the AMC shiplift, or a tailings storage facility (TSF) embankment in the Goldfields all demand a close visual inspection — and traditionally that means scaffold, an elevated work platform, or rope-access technicians. A drone inspection survey reaches the same surfaces in minutes, flies a repeatable path, and brings the inspector a sharper view than the naked eye from a cherry picker. This page covers how ISS delivers UAV visual inspection specifically for Perth and WA industry: the local assets, the method, the standards, and why a Perth-coordinated operator is the right partner.

Local applications: where Perth assets need inspecting
The density of heavy industry within an hour of the Perth CBD means a drone inspection survey Perth crew can image multiple asset classes in a single mobilisation, without the per-site standby costs that rope-access campaigns carry.
| Precinct | Operators / assets | Typical inspection targets |
|---|---|---|
| Kwinana Industrial Area | Alcoa & South32 Worsley alumina, BHP Kwinana Nickel, Cockburn Cement, Albemarle Kemerton, BP import terminal | Calciner and kiln stacks, conveyor gantries, storage-tank shells and roofs, digester structures, pipe racks |
| Henderson / AMC | Austal, Civmec, BAE Systems, Luerssen | Gantry and portal cranes, shiplift structure, fabrication-hall roofs, wharf superstructure |
| Fremantle & Cockburn Sound | Fremantle Ports, bulk terminals | Ship loaders, stacker-reclaimers, wharf cranes, jetty steelwork |
| FIFO WA (via Perth) | Pilbara iron ore, Goldfields gold, Kwinana feedstock mines | Headframes, transfer towers, crusher and mill structures, TSF embankments and spillways |
Kwinana stacks, kilns and tanks
The Kwinana Industrial Area is WA's largest industrial precinct and its assets are tall, hot and corrosion-exposed. Cockburn Cement's rotary kilns and preheater towers, the alumina calciner stacks at Worsley and Alcoa, and the tank farms across the BP and fuel-storage terminals all require external condition inspection that is slow and hazardous to do by hand. A drone inspection survey captures the full height of a stack or the entire roof of a 40-metre storage tank in one to two hours, geotagging every frame so coating breakdown and corrosion can be tracked between cycles.
Henderson cranes and wharf steel
At the Australian Marine Complex, the gantry and portal cranes and the shiplift structure operate over water and salt air. ISS uses long-range optical zoom payloads to inspect crane jibs, sheave assemblies and structural connections from a safe stand-off without standing down lifting operations — capturing detail a ground inspector simply cannot see.
FIFO mine and TSF assets
Perth is the mobilisation point for survey work across WA. Headframes, conveyor transfer towers and TSF embankments at Pilbara and Goldfields operations are remote, high and frequently live. Flying them from a Perth-staged crew avoids standing down production and produces a time-stamped baseline against which the next inspection is measured rather than guessed.
Key point: The commercial advantage in Perth is coverage density. A drone inspection survey can image a Kwinana stack, the adjacent transfer tower and a tank roof in the same window — work that would otherwise need three separate access setups. The fixed cost of mobilising a crew is spread across more assets per day than any scaffold or EWP campaign can match.
Method and equipment
A drone inspection survey is only as good as its optics, its stability in the Fremantle Doctor, and the discipline of the flight. ISS follows a structured, non-contact workflow refined across WA mining, processing and marine assets — typically half a day on site per asset plus one to three days of review and reporting.
- Scoping and risk assessment — We confirm the defects of interest (cracking, corrosion, coating, deformation), the required GSD, and whether photogrammetric geometry is needed. A JSA and a CASR Part 101 airspace assessment are completed, including the Jandakot and Perth Airport controlled-airspace constraints that affect much of the Kwinana–Henderson corridor.
- Ground control (where required) — If defects must be located on a 3D model or compared between inspections, ISS establishes control with Leica and Trimble GNSS and total-station equipment, tying the inspection to real coordinates.
- Flight planning and capture — The aircraft flies controlled passes at a fixed 3-10 m stand-off to hold a consistent GSD, using automated structure-following missions for complex geometry. High-stability multirotor platforms carry mechanical-shutter RGB sensors in the 20-45 MP class — resolving roughly 1-1.5 mm/pixel at 5 m, fine enough for hairline cracking and early coating breakdown.
- Optical zoom and thermal payloads — Where stand-off cannot be reduced — energised switchyards, hot Kwinana stacks, restricted exclusion zones — a long-range zoom captures detail from a safe distance, and a radiometric thermal sensor (<0.05 °C NETD) detects overheating bearings, wet refractory and electrical hot spots.
- On-site QA, processing and defect review — Coverage is verified against the asset map before demobilising, then imagery is processed into a tagged library, an orthomosaic of each face, or a textured 3D model. A competent inspector classifies defects by type and severity against the relevant standard.
Stand-off distance, not just megapixels, sets the achievable detail: a 45 MP sensor flown at 15 m resolves less than a 24 MP sensor flown at 4 m. The skill in a drone inspection survey is flying close and steady enough, safely, to capture the GSD the defect actually requires — and Perth's gusty afternoon sea breeze makes that discipline matter. ISS schedules close-range work for morning windows when Cockburn Sound winds are typically calmest.
Accuracy and standards
Two kinds of accuracy matter: how small a defect the imagery resolves, and — where geometry is captured — how precisely a defect can be located.
| Parameter | ISS specification | Typical benchmark |
|---|---|---|
| Image GSD (close range) | 1-3 mm/pixel | 5-10 mm/pixel |
| Smallest resolvable defect | ~0.5 mm crack width | ~2 mm |
| Defect location (georeferenced) | 20-50 mm | 100 mm+ |
| Thermal sensitivity | <0.05 °C NETD | 0.1 °C |
| Coverage completeness | 100% of nominated faces | Spot checks |
The inspection itself is conducted against the standard relevant to the asset — AS 4100 for structural steel, AS 3788 for in-service pressure-equipment external inspection, AS 1418 and AS 2550 for cranes and runways, and dam-safety guidance such as ANCOLD and the WA DMIRS code of practice for TSF embankments. CASA airspace and operational compliance is governed by CASR Part 101 and its Manual of Standards, and ISS records the standard applied, the inspector's competency and a measurement-confidence statement with every report.
⚠️ Watch out: A drone inspection survey does not by itself satisfy every mandated inspection regime. Some pressure-equipment, crane and dam standards still require hands-on or NDT inspection at defined intervals. Used well, a drone survey extends the interval between intrusive inspections and targets them — it does not blindly replace them. ISS confirms the regime that applies to your asset during scoping.
Why ISS for visual inspection in Perth
ISS is an independent industrial surveying firm — not tied to any aircraft brand or maintenance contractor — so the inspection serves your asset, not an upstream agenda. We operate under a current CASA Remote Operator Certificate with licensed RePL pilots, registered aircraft and aviation-endorsed public liability insurance, and we manage all CASR Part 101 airspace compliance, including the controlled-airspace approvals the Kwinana and Henderson precincts require.
Perth is our coordination point for WA. Our surveyors hold current WA mine-site passports and the construction and site inductions that Kwinana, Henderson and FIFO operations demand, so a drone inspection survey Perth clients book reaches site ready to fly. And because the same team that flies the UAV and aerial surveys also runs our engineering and mechanical work, when an inspection finds something that needs measuring we can bring a total station, laser scanner or photogrammetric capability to bear without re-engaging a new contractor. The drone inspection becomes the front end of a complete condition and dimensional picture — which matters in a state where the surveyor shortage is the most severe in Australia and a return mobilisation can cost weeks.
WA's coastal industrial environment makes repeatability the real prize. Salt air off Cockburn Sound and the daily Fremantle Doctor accelerate corrosion on Kwinana stacks and Henderson cranes well beyond inland rates, so annual visual cycles are rarely enough. A georeferenced drone inspection lets you inspect more often, for less, and measure deterioration rather than discover it during an outage.
Frequently asked questions
How quickly can ISS mobilise a drone inspection in Perth?
For assets in the Perth metropolitan area — Kwinana, Henderson, Fremantle and surrounds — we typically mobilise within a few days of scoping, subject to CASR Part 101 airspace approvals near Perth and Jandakot airports. For FIFO sites we align with your roster cycle and stage equipment in Perth before travel. Urgent post-incident inspections can usually be expedited.
Can you inspect Kwinana and Henderson assets while they keep operating?
Usually, yes. The capture is non-contact and most live assets can be inspected without standing down production, provided an exclusion zone can be maintained around people and operating plant. Energised switchyards and hot Kwinana stacks are flown from a safe stand-off using an optical zoom or thermal payload, so lifting and processing operations continue.
How accurate is the inspection, and does it meet Australian standards?
ISS captures 1-3 mm/pixel GSD on close-range work — comparable to a hands-on close visual inspection — and locates defects to within 20-50 mm where ground control is established. Inspections are classified against the relevant standard (AS 4100, AS 3788, AS 1418/AS 2550, ANCOLD) and every report carries the standard applied and a confidence statement.
Do we need our own CASA approval to use a drone on our Perth site?
No. As the operator, ISS holds the Remote Operator Certificate and manages all CASR Part 101 compliance, airspace approvals near Perth and Jandakot, and insurance. You provide site access and the relevant site inductions; we handle the aviation regulation end to end.
