I've been down there quite a few times. Until just a while ago, it used to go on for quite a way - but it's since caved in, or been collapsed. You can still get in probably 30-50 metres or so, but it used to go a lot further.
When you get inside, it opens into a chamber where you can pretty much stand, and continues off into a few smaller corridors on either side.
I've also heard the rumour about the Monks, but I doubt it's true. However, it is more likely to have been used by Bevan von Einem, when the man was killed at the dam. I interviewed some people that were once close to von Einem for a book I'm writing, and they admitted to using tunnels and drains for transport and storage, however didn't seem to admit to this one specifically.
For those of you chasing after the geo-cache, unfortunately, you'll probably find it missing, just as I did.
Please feel free to message me if you want to have a look.
