A 33-year-old woman is the first in Western Australia to be fitted with an electronic monitoring device for breaching quarantine order.
The woman was told to isolate for 14-days at her home in Perth after entering Western Australia on September 1, police said in a statement.
A Self Quarantine Assurance Team discovered two men visiting her home during a routine check on Thursday, while the woman was still under the self-quarantine order.
The woman has been moved to hotel quarantine and will be charged with a $1000 infringement fine for Failure to Comply with a Direction.
After considering the circumstances of the breach and the woman's previous history, the State Emergency Coordinator decided to monitor her location with an ankle device, the statement said.
The device will remain during the woman's remaining quarantine period. The Western Australia Government introduced the enforcement GPS monitoring equipment in April, as part of new laws under the COVID-19 State of Emergency.
In late August, Western Australia Premier Mark McGowan said those deemed a "flight risk" or those with a criminal history may be forced to wear the tracking device.
"If someone is identified as a risk, we have the legal power now to put an ankle bracelet on, that's what police will look to do," McGowan said.
The Western Australia Government has bought 200 electronic ankle bracelets so far, costing $3 million.
There were no new cases of COVID-19 in Western Australia on Saturday, and four active cases remain active.
