A caravanner has allegedly sped through a checkpoint on the Western Australia-South Australia border, before leading police on a dramatic high-speed chase.
Police say the woman, who was driving a Volvo wagon and towing a caravan, failed to stop at the Eucla quarantine checkpoint.
The ABC reports that police then gave chase with emergency lights and sirens, but the woman failed to stop and accelerated away. Police say she was seen to be driving erratically, which caused the caravan to move from side-to-side unpredictably.
As police approached the car, the woman allegedly put her car in reverse and rammed her caravan into an unmarked police car, a Toyota Prado, before angling her car towards an officer and driving at speed, which forced the officer to take evasive action.
Police told the ABC that the woman drove off on the wrong side of the road and headed into Nullarbor bushland, where the caravan eventually dislodged.
Police then followed at until she drove the Volvo into a truck rest bay about 40 minutes later.
After stopping behind her, police allege the woman reversed at speed towards them again, but they were able to avoid another collision.
Police maintained their distance until the woman eventually turned around and drove in an easterly direction back towards Madura Roadhouse, where she was taken into custody.
The ABC reports that a 47-year-old woman will face court today in relation to the incident.
