Дuring May 2022, Western Australia experienced sharply rising cases amongst the highest per capita cases seen anywhere in the world throughout the pandemic. Western Australia's low case numbers were attributed to a swift introduction of restrictions by authorities, a strict state border policy, and its isolation. Since then, there was only a handful of cases of community transmission in the state, until late December 2021 when a tourist caused an outbreak that led to the cancelling of some New Year's Eve events, and the re-imposing of mask wearing rules in Perth and the Peel region. By mid-April 2020, the state had eliminated community transmission of COVID-19, becoming one of the few places in the world to do so. On 24 March, Western Australia closed its borders to the rest of Australia, and on 1 April, the state implemented borders between regions in the state.
