BOM stated significant heat had affected large parts of central and southern Australia from mid-December as a slow-moving high over the Great Australian Bight allowed heat to build over the continent, with temperatures remaining elevated into the New Year period.

Last year was officially Australia's warmest and driest year on record and did set a number of weather records for Bega.
