  • Australia’s hottest summer day on record (7 January)
  • Australia’s warmest winter day on record (31 August)
  • Australia’s hottest month on record (January)
  • Australia’s hottest summer on record
  • Australia’s hottest January to August period on record

  • The warmest winter on record for Victoria
  • The warmest 12-month period on record for South Australia
  • The warmest winter day on record for the Northern Territory
