The COVID-19 pandemic has spread across WA, with the first cases recorded in the Kimberley, Mid West, Wheatbelt and Great Southern, as the State’s total increased by 35.

The new cases include two children, aged four and 10, from the same family, as well as eight passengers from the Ruby Princess cruise ship and four from the Ovation of the Seas.

WA now has 175 cases, with 11 patients in hospital, including four who are being treated in intensive care.

The testing regime in WA has also been expanded, with an “aggressive outreach” program targeting “geographically located areas where there is community transmission”.

Testing will also include, for the first time, testing of all disembarked cruise ship passengers.

Health Minister Roger Cook was unable to provide details on what routes the infected Swan Transit bus driver worked.

He said authorities were trying to identify what routes he drove and on what days.

The key concern is bus passengers who exchanged cash with the driver. Mr Cook said the risk to passengers who used a Smartrider card was “low”.

Mr Cook would not speculate on whether the driver had continued to work while he felt ill.

He said COVID-19 patients in regional who became seriously ill could be transferred to Perth hospitals by the Royal Flying Doctor Service.

The WA Government is not naming which regional towns or cities the coronavirus cases live in, citing privacy reasons. Instead, only the regions are named.

Mr Cook again warned that beaches or parks could be closed if West Australians did not comply with social distancing measures.
