Jay grab yourself some expanding foam, and some fibreglass. Bunnings sells both, but you're better off getting the fibreglass from a boat builder or another source (Bunnings fibreglass is $$$$$).
Put the foam down, give it 20 mins to expand, then it gets a skin, so you can push, mould, and create ledges and crevices. Once it dries (keep an eye on it - it keeps expanding), you can give it 3 coats of fibreglass and it'll be rock-hard. And safe. Put a couple of coats of stone-effect paint over it (dark first, then sponge a few lighter shades over the top) and you're all done.
Takes 2 days tops - i've put a pic of one of my jobs below. Sorry the pic isn't very good - i'll chase up a better one later on tonight to give you a better idea.

Hey thanks for the info and just a word about using fibreglass cloth, make sure you wear a good quality mask as it is GLASS you are breathing in and will cause all sorts of problems,but you probably new thatGreat job on your enclosure Mat - it looks fantastic!
Wattyl paints make Stone effect paint - there are a couple of other brands out there as well. Check out their website for colours - I used 'minotaur' for the main dark colour, and 'cement pot' for the lighter shading that I sponged on, with a little green for moss. The more colours you use, the more realistic it looks. You can mix a little white with the stone paint, and make a lot of different colours - put the darker colours on first, then gradually add lighter colours over the top.
You can use just the resin, but you'll need lots of coats to make it strong enough. If you grab some thin fibreglass sheeting, its really easy to push into the crevices - but I only used it on the flat surfaces that would get a little more use.
