Each year there are 1-2 known deaths from saltwater crocodiles (as well as 4-10 non-fatal attacks), usually highly publicised due to their viciousness and aggression. The longest croc ever measured and verified was 6.4m (21ft). It could have weighed more than 1000kg. In Australia, there are unverified reports of crocs up to 8m.

    The Sydney funnel-web spider is found within 100km of the city. In the tropics and subtropics, they favour rainforests and higher altitudes, but in southern states they live in drier eucalypt forests and woodlands, as well as snow country. Nobody in Australia has died from a spider bite since 1980 after the successful introduction of antivenom for all native species.

    Jellyfish account for more than 80 known deaths since 1883. The box jellyfish (pictured) was responsible for 79 deaths, and Irukandji the other two. Both jellyfish have tentacles that are generally invisible, can entangle you and have millions of harpoons that inject a lot of venom at once. The box jellyfish in particular is the only one on this list that can kill in minutes. Ergo, highly dangerous.

    All recorded bites by the inland taipan to date have been to snake handlers and no deaths have been documented. If the situation is handled calmly, it can take hours before a serious paralysing effect presents in an adult bitten by a taipan or other venomous Australian snake. Using immobilisation and bandage pressure, you can buy yourself hours, if not days to get assistance. It is better to stay put and send for a chopper than try to walk out of the bush when bitten.

    The blue-ringed octopus has blue blood, three hearts and enough poison to kill 26 humans. The same nerve toxins injected by a blue-ring are found in the flesh of fugu fish – a pricey delicacy beloved by the Japanese. The ingestion of fugu that’s not been expertly prepared leads to more hospitalisations than blue-ringed octopus bite. The blue-ringed octopus has only been attributed with causing three known deaths, but there have been no deaths since the 1960s and hospital admissions are exceedingly uncommon.
