Hey guys,
Thanks for all of the responses.
I have contacted Mt. Sylvia with regards to suppliers up here and I'm still in the process of chasing a few things up, but so far no luck.
I have been to Blackwoods and enquired about their diatomite and Kleensorb only to have them refer me to the Septone product (~$50-60 per bag), which I did a bit of research and found that it wasn't suitable (as mentioned here).
I will try Blackwoods again and see if they can get some Kleensorb up, and check any other sources that Mt. Sylvia recommends.
If I do find anything more reasonable (sub $40) between Cairns and Townsville I will post it here.
Cheers,
Rob
Edit*
Just jumped on Blackwoods site (which I should have done much sooner

)
They have Kleensorb listed as "Kleensorb Diatomite Green 20kg"

So it's off to Blackwoods.... again.
Thanks all
