Quick Summary

A coroner determined that Judith Anne Ditter's death from a falling tree branch in November 2020 near Stirling, Adelaide Hills, could have been prevented with earlier intervention. Acting Deputy State Coroner Ian White found that both the council and property owner had opportunities to assess and remove hazardous trees but failed to do so promptly. Recommendations are now being made to relevant government bodies for improving safety measures regarding large trees in development applications.

Story summary

In November 2020, Judith Anne Ditter, a 59-year-old South Australian school teacher, was killed when a heavy branch from a property fell on her car while she was traveling along Mount Barker Road in Stirling.

Acting Deputy State Coroner Judge Ian White found that Mrs Ditter's death, described as "sudden" and "shocking," could have been prevented with different actions.
