Cyclone Narelle hits Australia: logistics and safety lessons for mine operators
Reviewed by Tom Sullivan

First reported on MINING.com
30 Second Briefing
Tropical Cyclone Narelle, peaking at category 4 near Exmouth with forecast gusts to 165 km/h and heavy rainfall, has forced port closures at Ashburton, Cape Preston West, Dampier, Varanus Island and Geraldton, disrupting iron ore and LNG export logistics across Western Australia. Rio Tinto suspended port operations while maintaining mining and rail, Mineral Resources halted marine operations at Ashburton under its cyclone plan, and Fenix Resources scaled back non-essential mining and haulage amid diesel shortages linked to Middle East supply constraints. Westgold and Ramelius prepared for significant rainfall around Mount Magnet, with Ramelius planning short-term fuel sourcing from Perth instead of Geraldton.
Technical Brief
- Bureau of Meteorology guidance specified sustained winds near 120 km/h and gusts up to 165 km/h.
- Narelle was downgraded from category 4 offshore Exmouth to category 3 by Friday afternoon, then forecast category 2.
- Pilbara Ports implemented staged berth clearing at Ashburton, Cape Preston West, Dampier and Varanus Island from Tuesday night.
- Mineral Resources activated a formal cyclone management plan, including full suspension of marine operations at Port of Ashburton.
- Fenix Resources explicitly linked operational curtailment to compounded diesel shortages from Middle East conflict and cyclone-related logistics.
- Ramelius’ Mount Magnet preparations followed a standardised severe weather protocol focused on significant rainfall rather than direct wind impact.
- Narelle’s four Australian landfalls in one week illustrate multi-region contingency planning needs for fuel, ports and workforce movements.
Our Take
Pilbara Ports’ recent record throughputs of 71.2 Mt in December 2025 and 55.9 Mt in February 2026 mean even short cyclone-related closures at Port Hedland and Dampier can quickly translate into noticeable volatility in iron ore export schedules for BHP, Rio Tinto and Fortescue.
