It was the world's deadliest ever ballooning disaster until February 2013, when a balloon accident near Luxor, Egypt killed 19 people. As of July 2016, it remains the deadliest ever ballooning accident in Australia, and the third-deadliest worldwide, surpassed only by the Egypt crash and a balloon accident in Texas in 2016 that left 16 people dead.

WThis is a list of local government areas (LGAs) in Victoria, sorted by region. Also referred to as municipalities, the 79 Victorian LGAs are classified as cities (34), shires (38), rural cities (6) and boroughs (1). In general, an urban or suburban LGA is called a city and is governed by a City Council, while a rural LGA covering a larger rural area is usually called a shire and is governed by a Shire Council. Local councils have the same administrative functions and similar political structures, regardless of their classification. The sorting of LGAs into regions is for presentation purposes only, and has no legal or administrative significance.

WSevere Tropical Cyclone Orson was the fourth most intense cyclone ever recorded in the Australian region. Forming out of a tropical low on 17 April 1989, Orson gradually intensified as it tracked towards the west. After attaining Category 5 intensity on 20 April, the storm began to track southward and accelerated. The following day, the cyclone reached its peak intensity with winds of 250 km/h and a barometric pressure of 904 hPa (mbar). Orson maintained this intensity for nearly two days before making landfall near Dampier. The cyclone rapidly weakened after landfall as it accelerated to the southeast. After moving into the Great Australian Bight on 24 April, the storm dissipated.
