Louis, I remember Bundy from '92 when Ingrid and I sailed to Gt Keppel. The river was quite a walk up a big bank and not that far from the sea at Burnett Heads.
That is a huge amount of water. Some reports just said that it is flowing at 40 knots (80kph).
We're thinking of you and hope all works out ok.
I put an extra line through the mooring eye and around the mast for extra security if the deck cleat lets go. I think the weather will slip off the coast just south of Sydney so I don't think we will cop a fraction of what everyone else had.
Phillip and Shaun should have stayed in the lake.
Stay safe.
