Coroner's Finding: ROWE Stephen and HUNT Charmaine and HUNT Olivia and FERGUSON Peter (South Road Inquest)

Unknown·Stephen Rowe: atlanto-occipital fracture dislocation (broken neck); Charmaine Hunt: compound skull fractures; Olivia Hunt: atlanto-occipital fracture/dislocation; Peter Ferguson: bilateral rib fractures with haemothoraces - all from motor vehicle collisions

This inquest examined four deaths in three separate motor vehicle collisions on Main South Road at Cactus Canyon, South Australia between May 2000 and March 2002. All three collisions involved southbound vehicles losing traction on a wet, slippery road surface while negotiating a sweeping right-hand bend, crossing into the path of northbound vehicles. Skid resistance testing in December 2001 revealed dangerously low friction levels (0.36 mean grip number vs. 0.45 recommended intervention level), but this critical information was not communicated to regional staff responsible for the road until after the third fatal collision. A breakdown in internal communication, inadequate investigation, and failure to install appropriate warning signs meant motorists were not alerted to the hazard. Road resurfacing in June 2002 resolved the problem, with no subsequent collisions reported. The coroner found multiple systemic failures within Transport SA including poor data management, ineffective coordination between departments, and lack of initiative by investigating staff.
