I remember way back when, and it was reported in an adelaide newspaper at the time, that a tsunami was predicted to wipe out Adelaide and the then state premier Don Dunstan very famously stood on the end of the glenelg jetty to 'stop it' (to show what rubbish it was)
Anyway, looking around wiki i find this snippet:
One famous demonstration of Dunstan's charismatic style and media-savvy came in January 1976. A Jehovah's Witness soothsayer predicted that due to Dunstan and the state's social liberalisation—which he saw as sinful [121] —God would destroy Adelaide with a tsunami caused by an earthquake. [121] This was publicised by the media, prompting a not insignificant number of residents to sell their property and leave; some businesses had clearance sales while many who decided to stay indulged in doomsday parties. [121] Dunstan promised to stand on the seashore at Glenelg and wait for the imminent destruction. He did so on 20 January, the day of the predicted storm, and nothing happened, although he made newspaper headlines in the United Kingdom for his defiance. [121]
The [121] is reference to a book published in 2000:
Adelaide : a sense of difference /? Derek Whitelock with Tony Baker ... [et al.]. Author
Whitelock, Derek, 1934-
I have never heard that bit...anybody know anything?
