Contact with living things (known as Exposure to animate mechanical forces in ICD10-AM coding) includes injuries caused by humans, animals and plants including bites, stings, envenomations as well as unintentional person-to-person contact. It also includes exposure to or contact with animal allergens (allergy to animals).
This category includes only unintentional cases of injury hospitalisation or death. Intentional injuries are included under Self-harm and suicide or Assault and homicide.
Hospitalisations record the principal cause responsible for the injury, classified according to ICD-10-AM codes in the W50-W64, X20-X29 and Y37.6 ranges.
Causes of injury
In 2023–24, hospitalisations most often resulted from the following causes (Figure 1):
- bitten by dog (9,691 cases, 36.1 per 100,000 population)
- hit, struck, kicked, twisted, bitten or scratched by another person (5,807 cases, 23.0 per 100,000 population)
- bitten or struck by other mammals (5,330 cases, 19.0 per 100,000 population)

- ASR is the age standardised rate per 100,000 persons.
- Only causes resulting in more than 100 hospitalisations in 2023–24 are shown. For a comprehensive list of all causes, refer to supplementary data tables.

Types of living things can be further categorised to indicate whether venomous or not. Injury hospitalisations related to venomous animals represented about 7% of all contact with living things hospitalisations (for records where venomousness was known).

Trends over time
There is a break in the time series for hospitalisations between 2016–17 and 2017–18 due to a change in data collection methods (see the technical notes for details).
The age-standardised rate of injury hospitalisations caused by contact with living things has increased from 101.3 to 123.4 per 100,000 population over the past decade (Figure 3). Between 2017–18 and 2023–24, the rate increased by an annual average of 2.5%.

The number of deaths caused by contact with living things has generally remained stable over time, fluctuating between 24 and 36 deaths per financial year over the past decade. Age-standardised rates are not presented due to small numbers of deaths. (Figure 4).

Trends varied depending on the type of living thing involved (Figure 5). Among the top five causes of injury hospitalisations due to contact with living things, hospitalisation rates from being bitten or crushed by snakes, unknown whether venomous or nonvenomous, changed the most (13% increase) in 2023–24 compared to the previous 5-year average.
Injury hospitalisations from being bitten by dog(s) showed the second largest increase (12%), and have generally increased steadily over the past decade, with age-standardised rates more than doubling between 2014–15 and 2023–24.
Hospitalisations caused by unintentional human-to-human contact have mostly remained stable over the past 10 years, while hospitalisations resulting from contact with venomous spiders have steadily decreased over the same period.
