The second fastest flowing river in the Southern Hemisphere is The Don River in North Queensland (Bowen) in Australia. It rarely does flow, but when it does, it's powerful. I'm from Bowen myself and have seen it. We have always been told that it is the second fastest and i believe The Clutha River in the Southern Island of New Zealand is the fastest.

The fastest part of a river is the narrowest or shallowest. In broad, deep sections the water moves slowly, in narrow or shallow sections the river moves fastest. Of course the fastest flowing water is at a waterfall or rapid.
