Coincidentally, what was probably the first visual sighting of this phenomenon was also made in Australia - in 1893!
"On the evening of February 4, 1893, J. Ewen Davidson was watching a distant thunderstorm in Queensland Australia. Twenty to twenty-five times he saw 'a patch of rosy light' mount upward from the stormclouds and vanish. In addition to these patches he also saw a few pale streamers beam upward from the clouds."
