AI-generated summary
Two children, Jack Craig Anstey (7) and Ashleigh Fiona Mungur (8), drowned on 3 October 2003 when the Jeep Cherokee in which they were passengers was washed from a low-level ford crossing of the Blackwood River on Jalbarragup Road near Nannup, Western Australia. The driver, Craig Anstey, and front passenger Clare Smyth escaped, but the children could not. The coroner found that water depth was approximately 1.3 metres with strong, non-visible currents. The crossing lacked adequate warning signage about hidden hazards and powerful currents. A key investigative issue was whether amphetamine use affected Anstey's judgment; while not definitively proven due to evidentiary gaps, multiple witnesses observed post-incident symptoms consistent with amphetamine use, and Anstey had a documented history of regular use. The coroner made an open finding, finding the deaths not preventable in a strict sense but highlighting systemic failures: inadequate road signage, insufficient Road Traffic Act provisions for compulsory drug testing in fatal crashes, failure to secure the crash scene, and Main Roads' decision not to fund a permanent bridge despite exceptional safety risks.

Drugs involved
Contributing factors
- Low water level crossing inadequately warned of strong currents and depth hazards
- Inadequate depth markers and signage
- Driver did not adequately assess water depth and conditions before attempting crossing
- Possible amphetamine use affecting driver judgment
- Vehicle engine stalled in deep water, leaving occupants unable to escape
- Possible prior amphetamine use and cognitive impairment
- Absence of compulsory drug screening after fatal incident
Coroner's recommendations
- Amend the Road Traffic Act 1974 section 66 to permit police to obtain compulsory blood samples from drivers in fatal traffic crashes to determine whether drugs or medications contributed to the incident, regardless of apparent intoxication at the scene
- All road authorities review low-level crossings within their control and conduct risk assessments to ensure adequate signage and appropriately located depth indicators
- Consider exceeding basic Australian Standards for signage in cases of unusual or hidden hazards, particularly at ford crossings with strong currents and significant depth
- Ensure depth indicators are placed at locations where they will not be dislodged by floodwaters
- Commissioner of Police provide additional training to officers on preserving accident scenes and monitoring Road Traffic Act time limits for sample collection
- Ensure police monitoring of scene investigations to prevent unauthorized removal of evidence from vehicles
- Main Roads Western Australia reconsider its decision not to fund a new bridge crossing the Blackwood River on Jalbarragup Road in light of the exceptional dangers posed by the low-level crossing and its inadequacy despite improved signage
