A National Parks and Wildlife Service supervisor has told a coronial inquest into the Black Summer bushfires he raised concerns about changing weather conditions and spotting in the hours before a back-burn in the Blue Mountains broke containment lines.
Air attack supervisor Chris Banffy had been conducting aerial surveillance of the Gospers Mountain "mega-blaze" in December 2019 when the Rural Fire Service (RFS) Incident Management Team (IMT) decided to proceed with a back-burn in the Grose Valley/Mount Wilson area.
