"The Bulahdelah Tornado was an intense tornado which occurred near the town of Bulahdelah (100 kilometres (62.1 mi) north-northeast of Newcastle), New South Wales on 1 January 1970, and is thought to be the most destructive tornado ever documented in Australia.[1] It is thought to be least F4 or F5 on the Fujita scale however no official rating has been made public.[2][3]


How acurate do you beleive this information to be?

The synoptic charts posted above are impressive to say the least. How often would a setup like this or similar occur in Australia?

It is interesting that they state this, I thought the Bucca tornado rated F4 was the supposed to be the most powerful.

BoM states

The most intense tornado recorded in Australia - with a Fujita rating of F4 - occurred at Bucca, west of Bundaberg (Queensland), on 29 November 1992. The intensity of the winds created freak effects, such as embedding a picture frame in the wall of a room. Hail the size of cricket balls accompanied the storm.

So if the Bulahdelah Tornado 22 years earlier was supposed to be F4-F5 I would have thought along the lines that maybe BoM would have stated it to be equal or stronger than the 1992 Bucca tornado or vice versa. Its interesting. Would be good to have more info.
