Brickie,
I've been comparing prices near Greenville, South Carolina.

Portland cement is $11 for a 94#bag and Vermiculite is $15/bag (4 cu.ft ?).
Figuring a 20 sq ft area that is 4" thick gives me a volume of 6.7cu ft. If I plan 10 cu ft, I'm looking at $50 for two bags of vermiculite (8cf) and 3 bags of portland cement 1.8 cu ft and (assuming 5:1 vermiculite: portland cement). I've tried to account for some compaction in this estimate too.
Even if I go to 6" thick, I'm looking at $75. Still a lot less expensive than Duraboard - but does require more labor.
Obviously I don't know about prices in Australia, but wouldn't mind vacation there!
Jeff
