In Asutralia Coroplast is called Corflute - I live in Qld and it cost me only 13 dollars for a huge 2x1 metre sheet that was 5mm thick - the cubes I found in Bunnings in the storage section being sold in packs of 5 for 11 dollars - so all in all these cages are not only practical, large, ideally suited etc etc - they're also CHEAP!
