Accidents and serious incidents (commonly called Immediately Reportable Matters), which affect the safety of aircraft must, in the first instance, be notified to the ATSB by telephone toll-free call: 1800 011 034.

In addition to the above statutory requirement, it is a Gliding Australia requirement that Immediately Reportable Matters are also reported to the Gliding Australia Executive Manager, Operations (EM/O) or the Chairman of the Operations Panel (COP) at or around the time they are reported to ATSB. The telephone contact details for the EM/O and COP can be found on the Gliding Australia website. The EM/O or COP will notify the appropriate Gliding Australia officers and the Regional Manager Operations of the relevant Region.
