Key points:Staff in WA's quarantine hotels say rule breaches are occurring regularlyDoctors say the reliance on private security contractors is alarming
The WA Premier says he has been advised the system is "working well"
The concerns from workers within WA's hotel quarantine follow revelations of major flaws with the operation of Victoria's system, which has been blamed in large part of Melbourne's escalating COVID-19 outbreak.In multiple interviews with employees directly involved in WA's hotel quarantine system, who spoke to the ABC on the condition of anonymity to protect their jobs, staff revealed major breaches and warned little action was being taken to address issues when they emerged.
"It is mayhem and the handling of it is disgusting," one staff member said.
"It is like a time bomb."
Among the issues raised were:A near-total reliance on private security contractors for monitoring guests, with police only attending hotels when called out or when looking for a specific personRepeated face-to-face interactions between quarantine arrivals and staff members not wearing full protective gearRegular breaches of rules governing which parts of hotels staff members who interact with quarantine guests are allowed to accessBreaches not being reported for hours, if at all
Minimal action being taken to rectify issues when they emergedHotel staff members refusing to work out of fearRegular threats and abuse of staff members by quarantine guests. "
