Really nice photos there Michael! Northern Rivers has started well this season, hopefully a sign of things to come after a poor last season.
Some photos of the storms across NE NSW this afternoon. First pics taken around 1430 west of Grafton with the rest east of Guyra/Armidale shortly after. All shots taken at around 36,000 feet.

This was the last storm on the southern edge to the ESE of Armidale. Nice structure!

The photo below is the monster storm 300kms off the coast of Port Macquarie. Very nice overshoot!
