The exact routes driven by a Transperth bus driver infected with COVID-19 have been revealed, as it emerged more than 130 passengers exchanged cash with him.

The WA Government said 137 passengers paid in cash across the driver’s eight shifts from March 9-18, before he stopped work on Thursday when he felt sick.

The Health Department advised that transmission of the disease via the handling of cash was “low risk”.

But passengers who used cash — and may have had incidental contact — can check the bus routes and the time he was driving if they held concerns.

“Even though the risk is low, the State Government understands there may be increased anxiety for these 137 passengers and is therefore releasing details about the routes and times driven by the bus driver,” a Government spokesman said.

“If these passengers do experience fever or respiratory symptoms, they should take precautions and seek medical advice.”

The driver works for Swan Transits, which operates routes on behalf of the Public Transport Authority. Between, March 9 and 18, he drove the following routes:

506: Bull Creek Station to High Rd / Nicholson Rd

507: Bull Creek Station to Cannington Station

517: Murdoch Tafe to Thornlie Station

178: Bull Creek Station to Elizabeth Quay bus station

999: Circle route from Fremantle Station to Fremantle Station

518: Murdoch Tafe to Cockburn Central Station

527: Cockburn Central Station to Aubin Grove Station

537: Aubin Grove Station to Honeywood Av / Darling Ch

The driver returned from an holiday in the United States on March 7, before the 14-day self-isolation period requirement came into effect.

He booked off work as soon as he felt sick and on Monday returned a positive test for COVID-19.

“The Department of Health has advised that passengers who travelled on the same vehicle as the driver are defined as “casual contacts”. This is particularly the case for the large majority of passengers that used a SmartRider,” the Government spokesman said.

“According to health guidelines, casual contacts don’t need to be concerned and do not need to be excluded from work or school, unless they become unwell, which is the health advice for every Western Australian. They should closely monitor their health, and if any symptoms are experienced they need to seek medical advice.”

The driver was believed to have been exposed to the virus while overseas and there was no evidence he contracted the illness while in Australia, a safety notice posted at the Swan Transit’s Canning Vale depot said.

Swan Transit was now reviewing CCTV and contact tracing was under way to identify anyone who may have been exposed to the potentially lethal disease.

“Those affected will be contacted by us or the relevant health authorities. It is incredibly important to follow any health advice you receive,” the notice stated.

Increased sanitation measures were introduced 10 days ago in consultation with the Public Transport Authority and every bus driven was required to sanitise each evening.

The buses the driver had contact with at work would also be sanitised again as a precaution, staff were told.

“It is also a reminder to follow all of the strict health guidelines with regards to any symptoms you might be experiencing,” the notice continued.

“This remains a challenging time for all businesses, including essential services like ours. We appreciate your care, and please know that we are absolutely committed to ensuring best practice for our drivers and the community.”

Mark McGowan said he had been told about the positive result on Tuesday morning. “He has been overseas, he went back to work,” the Premier said.

“The clear message out of all of this is: if you are unwell, if you’re sick — don't go to work, particularly if you've been overseas. This is very regrettable.”

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

Swan Transit declined to comment for privacy reasons. The Public Transport Authority referred questions to the Health Department, who have been approached for comment.
