Australian insurers and government agencies are preparing for an extended period of severe weather as Tropical Cyclone Narelle intensifies off the Queensland coast and moves toward Cape York, with forecasters warning it could be the most significant system in decades for some communities. Narelle developed on March 17 south of the Solomon Islands and by March 18 had strengthened to a category 3 cyclone tracking toward far north Queensland.
The Bureau of Meteorology (BoM) said the system had a high probability of continuing west and crossing the coast near Coen on March 20. BoM meteorologist Sue Oates said current estimates indicated very high winds near the cyclone’s centre. “An estimate of wind gusts at that time is about 200 to 250 km/h, noting that’s the intense core around the eye of the system, with the destructive winds extending out from that core,” Oates said, as reported by The Guardian. Oates also pointed to risks from intense rainfall, flash flooding, and strong tides.
Queensland Premier David Crisafulli said emergency services resources were being deployed into the region ahead of the expected landfall. Lizard Island has been largely cleared of visitors, with essential staff remaining under cyclone plans, and vulnerable residents in the path of the system – including people needing dialysis and pregnant women – are being flown out. “This may be the biggest system that many people have seen in living memory, and that’s why we’re asking people to prepare as we have,” Crisafulli said, calling on communities to use the available time to secure properties or leave if advised. Queensland Police disaster coordinator Chris Stream highlighted the danger from debris during the peak of the storm. “This is not the opportunity for you to be outside during the cyclone, getting that TikTok moment. Do not do it. A piece of debris being propelled at 100km [an hour] or more will likely kill you,” Stream said.
Updated BoM guidance indicates Narelle could make landfall near Coen on Friday morning as a category 4 system, then cross Cape York and move into the Gulf of Carpentaria. Senior meteorologist Jonathan How said the cyclone was expected to maintain strength over water, with a likely re‑intensification from category 1 to category 3 before a second landfall on Saturday night. How said the system was then likely to weaken into a tropical low as it tracks west but still bring heavy rainfall across the Northern Territory’s Top End, where catchments are already saturated after earlier events. Some regions, including Katherine and Daly River, remain in recovery from recent flooding. One scenario being monitored is that the system could move offshore again and re‑intensify before a potential third landfall in Western Australia early next week.
In Darwin, BoM meteorologist Jude Scott said the system was likely to move across the Top End on Sunday, bringing high daily rainfall totals near its centre. She said: “Given the already saturated river catchments right across the Top End, this rainfall will likely lead to renewed river rises.” Northern Territory emergency agencies noted that Narelle would be the seventh significant weather event of the current wet season. NT Police incident controller Kirsten Engels said communities should not postpone preparations. “Begin your preparations now and take this really seriously. We are going to get through this,” Engels said.
A flood warning remains in place for Katherine. Engels said relocating the town was “not on the table right now but that’s not to say it won’t change.” NT Emergency Service deputy chief officer Greg Jarvis urged residents to complete emergency kits and review cyclone plans and local shelter options. He said: “Take a big deep breath… we have to go again.” Under BoM definitions, category 4 cyclones, with average maximum winds between 160 km/h and 199 km/h, can cause major roofing loss, structural damage, destruction of caravans, and widespread power outages. Category 5 systems, with winds from 200 km/h and above, are described as “extremely dangerous with widespread destruction of buildings and vegetation.” Cyclone categories are based on wind speed alone and do not capture flood or storm-surge hazards, which are key drivers of insured losses.
The Australian Reinsurance Pool Corporation (ARPC) has designated Narelle as a Declared Cyclone Event under the Terrorism and Cyclone Insurance Act 2003, triggering the cyclone pool framework for participating insurers. ARPC said the declaration followed notification from the BoM that Tropical Cyclone Narelle commenced at 4pm (AEST) on March 17, 2026. The event has been allocated the code 20260317‑Narelle for reporting and aggregation purposes.
The start time notified by the BoM also marks the beginning of the relevant claims period under the cyclone pool arrangements, which apply to eligible household, strata, and small business property policies. ARPC said it would advise the cyclone end date and the corresponding claims period end once the BoM confirms that Narelle has dissipated or moved beyond the defined cyclone region. The declaration provides a common reference point for event coding, loss accumulation, and potential reinsurance recoveries related to Narelle and any subsequent re‑intensifications that remain within the ARPC definition of the cyclone period.
IAG – with brands NRMA Insurance, RACQ Insurance, CGU, WFI, and ROLLiN’ – said it has activated its major event protocols and is monitoring Narelle’s projected track across northern Australia. IAG meteorologist Kathryn Turner said the group’s 24/7 major event response and natural perils teams are tracking the system as it approaches Cape York. “We’re currently in the peak of cyclone season, and Tropical Cyclone Narelle may intensify into a category 5 system before it makes landfall across the Far North Queensland's Cape York on Friday. Cyclones of this intensity can bring abnormally high tides, destructive winds of up to 200 kilometres per hour, and intense rainfall that may lead to flash flooding. Destructive winds pose a significant danger to people, homes, and critical infrastructure,” Turner said. IAG is using its Situation Awareness Map (SAM) platform, which combines real‑time hazard data with policy and exposure information. The system is being used to identify potential impact areas and to position claims consultants, assessors, and repair networks ahead of a likely increase in claims.
IAG executive general manager claims Luke Gallagher said the period before landfall was important for people in at‑risk areas to complete practical preparations while conditions permit. “Safety should be the number one priority for people potentially in the pathway of the cyclone. Check on your neighbours, have an emergency plan in place, and make sure you have a plan for pets. Always follow the advice of emergency services and stay up to date with the latest information,” Gallagher said.
Gallagher added: “To help prepare your property for extreme weather, we encourage people to clear gutters, downpipes, and drains to prevent rainwater overflow into their homes. Preparedness is our best defence. While it is still safe to do so, take simple steps around your home that can help minimise damage. Secure loose backyard items to reduce the risk of strong winds lifting outdoor furniture and trampolines, trim overhanging trees and branches around your home, and clean up debris around your property.” He said IAG’s claims team will handle claims once conditions are safe and access to affected regions is restored, with customers able to lodge through the group’s various brands.
