Tidal bore in croc infested waters of NW WA?
The pic looks like a standing wave, my recommendation would be one of the rivers fed from the great dividing range where they do white water kayaking, eg Nymbodia. Don't get lodged under a tree branch or knocked unconscious on a rock and drown though. Alternatively, maybe there is a weir on one of these rivers that produces a standing wave, again dont drown.
Other option is in high intensity rainfall look for big stormwater outlet and you may find something but also contract hepatitis or leptospirosis.
