It gives me great pleasure to announce that tornadic activity has been observed in Australia, more precisely at a small community called Dunoon (near Lismore) in New South Wales.
The tornado (possibly an EF-1) was filmed by various residents in the area and storm-chased by Jimmy Deguara of australiasevereweather.com.

And still, the media continues to call it a "mini-tornado". I wanted to throttle the woman on The Today Show who said so. A weak tornado, yes, mini-tornado, ABSOLUTELY NOT.
