Another major event in recent years is this Australian tornado! Unbelievable event with storm damage destroying homes and a church in Dunoon, northern NSW in October 2007. The tornado also hits the substation and causes a spectacular explosion! Luckily, nobody was injured or killed!

Severe storms affected the Hunter Valley region but most storms of more significant severity producing large hail were near the Karuah to Bulahdelah region. Hailstones to 3cm were widespread along this path perhaps larger in the main core as these hailstones were falling predominantly ahead of the main core in the anvil region.
23rd February 2009
A severe storm on Monday 23rd February exhibited classic supercell structure with very definite hailstones! The structure did not last for long before it went into a slow decline. Nevertheless althoguh Sydney area did not have any storms predicted storms did develop further west. Twice the storm tried to organise before basically sending up an impressive explosive updraft and organising rapidly.
21st February 2009
Several storms were reported with storms rapidly developing near 
Lithgow initially and also east of Mudgee a little later. There were likely two supercells out of this region. The Lithgow cell had an interesting base – this nice image of a base circulation and dimple of a funnel almost overhead. This coincided with a wind change in the near storm environmental boundary.
This storm eventually moved towards but narrowly bypassed Singleton with very large hailstones. Another severe storm passed in the hinterland west of Muswellbrook – both this and the Singleton storm were likely supercells producing very large hailstones.
February 10 2009
Hailstorms Lithgow to near Lake Macquarie. The storm that approached Lake Macquarie was a fast moving storm and dumped hailstones to a diameter measured at 4cm. 
It most likely was an elevated supercell and was interesting to watch as it altered its local environment suddenly clearing the low cloud as it raced across.
Another sharp right moving storm approached Lithgow from near Mudgee and produced hail damage in Lithgow!
December 21st 2009 Singleton hailstorm
Very large hail was observed as a long lived supercell tracked the Putty Road north of Sydney and hitting Singleton head on causing extensive damage. 
January 10th 2010 Supercell Putty Road
Severe storms developed over the Putty region exploding to another level regardless of the weaker wind shear. Despite the warmer atmosphere, large hail was observed with microbursts near Jerrys Plains.
January 14th 2010 Supercell Walcha
High CAPE dominated on this day and although wind shear was relatively weak, the supercell attained excellent structure with deep layer inflow. A nice beaver tail observed for some time before the storm became outflow dominant. Lightning activity was incredible with a few sparkes on power lines observed. Large hailstones to 3cm were observed.
February 27th 2010 Classic Supercells with hook echos!
Several supercells developed on this day with hook echo featuring on at least 4 of these supercells – never experienced on any Australian radar to this date! Very large hail was observed smashing windshields in the Portland region.
