Veronica,

The Cabaret cave is specifically for functions and weddings, mine was 5 and a half years ago and the second one to be held in the cave, it has come along way since then. If you PM me, I will send you a link the the hire page etc..

Like I said it was absolutely fantastic and I love looking back on my photos as it is something different. You can also get accommodation at the Yanchep Inn for the night and you can get amazing photos there too.
