Christmas eve this year will be 50 years since Cyclone Tracy almost destroyed Darwin. Was that CC?
Althea was earlier still:
Severe Tropical Cyclone Althea was a powerful tropical cyclone that devastated parts of North Queensland just before Christmas 1971.One of the strongest storms ever to affect the Townsville area, Althea was the fourth system and second severe tropical cyclone of the 1971–72 Australian region cyclone season.
Both severity and regularity of cyclones has decreased ever since.
