A woman is behind bars for allegedly sneaking into WA despite having permission to enter.
Police allege the 28-year old WA resident travelled undetected by road to WA from Victoria between July 30 and this Tuesday before being located at her partner's Scarborough home.
Police allege the woman, from Ascot, was granted an exemption to enter the State on a flight from Melbourne on Tuesday but was told she would be need to quarantine in a hotel for 14 days at her own expense.
When she failed to arrive on at Perth Airport police started an investigation and found her later that day.
Police believe she snuck past the border checkpoint by hiding in a truck and are investigating whether anyone assisted her.
She has been charged with one count of failing to comply with a direction of the Emergency Management Act.
She was due to face Perth Magistrate's Court today.
Police said vast majority of the WA community was doing the right thing.
"However, everyone is reminded of their obligations to comply with any given direction when entering the state," a spokesperson said.
"Anyone who is found to be assisting an individual to breach a direction, may commit an offence under the Emergency Management Act 2005, punishable by imprisonment for up to 12 months or a fine of up to $50,000 for individuals and $250,000 for bodies corporate."
