Premier Mark McGowan has expressed confidence the extra $3.2 billion being pumped into the state health system will help Western Australia ride out an expected spike in COVID-19 cases following its reopening, despite ongoing warnings hospitals and health workers are already stretched to the limit.

Prior to reinstating masks in all public indoor settings in Perth on Sunday following five local cases, Mr McGowan said the additional funding this financial year would add 530 hospital beds, or “the equivalent of building a new tertiary hospital”.
