Vander Sanden snuck into WA in early August after hitching a ride with a truck driver she met at a Mildura roadhouse.
She hid in a car inside the truck as it passed through the border checkpoint, and was then dropped at a petrol station to be collected by a friend.
She then “shacked up” with the friend at his Scarborough unit and ignored police’s attempts to contact her to establish her whereabouts after she failed to arrive in Perth by plane on August 11, as expected.
Her lawyers argued she should have received a fine while state prosecutors pushed for jail time.
The maximum penalty for failing to comply with a direction under the Emergency Management Act is a $50,000 fine or 12 months imprisonment.
