The only website that has super high tides in Australia is an Australian one - all the rest (worldwide) have Bay of Fundy, Ungava Bay and then Avonmouth/Bristol Channel as top 3
Broome has big tides but sub 10m as a highest tide (not a tidal range)
As an update - found King Sound not too far from Broome with 11.5m - Bay of Fundy quoted as 16.5m and Severn Estuary as 15m
