If anyone is interested in getting some pumice I am planning a trip in the future to go down to Sydney to pick up a ute load of bags of 1-7mm from Australian perlite.
I can organiZe meeting people in Newcastle to pick up their bags of pumice if they like.
Depending on how many people I get will determine the price per bag, the only extra cost I will be putting on the bags is fuel and maybe Big Mac for myself for lunch (jokes)
Feel free to PM me of you like.
The going price for pick up per bag last time I checked was around $18, but I will need to confirm that, but that gives you a rough idea.

Your pricing is spot on, I just bought 2 bags myself this week
