Hospital admissions for injuries due to other unintentional causes appear to display a weak seasonal pattern, typically peaking over winter and declining over the warmer months.
In March 2020, the first lockdowns and social distancing measures associated with COVID-19 interrupted the usual activity of many Australians. The restrictions to movement and activity coincided with a sharp drop in overall injury hospitalisations. For this category, there were 31% fewer admissions from March to May than the in same period of the previous year. As initial restrictions eased, admissions rose in May and June, though they remained below previous levels.
See the interactive COVID-19 display for data and further discussion about the impact of COVID-19 on hospital admissions.

Notes
1. Months have been standardised to 31 days.
2. A scale up factor has been applied to June admissions to account for cases not yet separated.
