This is the middle cascade of the magnificent National Falls, Royal National Park, NSW Australia. Taken in the late evening during that magic time when the flowing water gets a blue tint to it.
There are three tiers to the falls and each one gets longer as you go down. This one is about 30m high but the bottom one would be at least 100m. It’s really hard to get to and I’m just waiting for some torrential rain to go back and get it. It’s a fascinating trip – you have to actually walk behind the falls to get to their base.
Here’s a shot of the top cascade:

and here’s a shot of the base of the middle cascade just after dusk (when the water goes that magic blue for about 20 minutes)
