Cairns

Is Cairns safe?

Yes, for a reef or rainforest trip, as long as you take the tropics seriously. Murders are rare: Queensland Police recorded 7 in the Cairns council area over the three years 2023 to 2025, about 1.3 per 100,000 people a year among 179,000 residents. Crime that touches visitors is more common than in southern cities, though. In the year to September 2026 Cairns recorded assaults at nearly three times the Brisbane council area's rate per resident, and break-ins to homes at four times.

The natural risks are what really set Cairns apart: wet-season cyclones and floods, saltwater crocodiles and dangerous jellyfish. We score Cairns 77 out of 100, below the Gold Coast and Brisbane (both 83).

Stingers, crocodiles and where to swim

Cairns is not a city where you simply walk into the sea. The Queensland Government says box jellyfish and Irukandji are present in tropical waters all year round, with the highest risk in the stinger season from November to May. Irukandji are tiny, and their sting may take 20 to 40 minutes to cause symptoms, so treat any sting seriously.

Saltwater crocodiles live along the same coast, in rivers, creeks, mangroves and on the beaches. The state's record of attacks since 1985 shows no deaths in Cairns itself, but it lists non-fatal attacks at Lake Placid on the Barron River (2021), the Barron River (2004) and Yorkeys Knob (1996), and fatal ones at Craiglie Creek near Port Douglas (2017) and Thornton Beach near Cape Tribulation (2015).

The official advice is simple:

• Swim in the stinger nets at patrolled beaches, or in a pool. Consider a full-body lycra suit in the water.
• If someone is stung, call 000, pour vinegar on the sting and start CPR if needed.
• Obey crocodile warning signs, and assume crocodiles are present even where there is none. Do not swim in rivers or creeks, keep well back from the water's edge and take extra care at night and in the September to April breeding season.

Answer it honestly.

Break-ins and theft

Theft is the crime visitors are most likely to meet. In the year to September 2026, Cairns police recorded 150 robberies, about 84 per 100,000 people, plus 1,219 car thefts and 2,718 break-ins or attempted break-ins to homes. Per resident, robbery runs at about 1.5 times Brisbane's rate, car theft at about twice and home break-ins at about four times. Robbery was lower than in 2025, when police recorded 205.

For a visitor that means locking up properly: shut and lock windows and sliding doors in a holiday rental even when you are home, keep car keys out of sight, and leave nothing in a parked car, especially at beach and trailhead car parks.

Cairns at night

Gallup's 2025 report finds 66% of Australians feel safe walking alone at night. Cairns has more trouble after dark than the big southern cities: the Cairns police division, which covers the city centre, recorded 2,672 assaults in the year to September 2026, against about 1,100 in Brisbane's Fortitude Valley. The figures include domestic violence, which visitors rarely meet, but the gap is still large.

The waterfront and the busy restaurant streets of the city centre are fine in the evening. Late at night, avoid arguments outside bars, do not walk alone through parks or quiet back streets, and take a taxi or ride app home.

Cyclones, floods and the wet season

Cyclone season runs from November to April. In December 2023, Cyclone Jasper crossed the coast as a category 2FAA IASAThe US FAA's check of whether a country's aviation regulator meets ICAO standards. Category 1 means it does; Category 2 means it does not.More in the glossary system near Wujal Wujal, about 120 km north-north-west of Cairns. The rain that followed was worse than the wind. According to the Bureau of Meteorology, many places had more than 1,000 mm in five days, Mossman recorded 714 mm in a single day, an Australian December record, and the Barron River at Cairns Airport rose to an estimated 4.4 m, above the 1977 flood level of 3.8 m. Floods, landslides and road closures followed across the region, and whole communities were evacuated.

If you travel in the wet season, book refundable tours and accommodation, watch Bureau of Meteorology warnings and never drive through a flooded road. The wet season is also mosquito season: the Queensland Government says towns in north Queensland that have the dengue mosquito are prone to outbreaks when travellers bring the virus in, and that this mosquito bites during the day. Use repellent and cover up.

Roads and getting out of town

Queensland's crash data show 7 road deaths in the Cairns council area in 2024, about 3.9 per 100,000, and 30 over the five years 2020 to 2024. That is a little above Brisbane's rate. Many visitors drive north to Port Douglas, the Daintree and Cape Tribulation or up to the Tablelands; those trips leave the city, so allow time, avoid driving tired and check for road closures in the wet season.

The air is clean and tap water is safe. Dial 000 for police, fire or ambulance.

How we scored it

Health and environment (88) and violent crime (82) are Cairns' strongest factors; murder is rare, though assaults are common. Natural hazards (62) is the weakest, because of cyclones, record floods, crocodiles and marine stingers. Theft (72) reflects break-in and car theft rates well above Brisbane's, and night safety (70) sits four points below Brisbane on the same Gallup share because of higher assault and robbery rates.
