When did 4 of the 12 apostles fall in Victoria?

The phrase "4 of the 12 apostles" refers to the Twelve Apostles, a collection of limestone stacks located along the Great Ocean Road in Victoria, Australia. These natural formations are not actually related to biblical apostles but are named for their majestic appearance. The stacks were formed through erosion and are believed to have started to fall due to natural processes over the years, with significant collapses occurring in 2005, 2009, and 2017. The most famous of these collapses was the collapse of the "London Bridge" formation in 1990.
