I've always wanted to try the sandstone rubble technique for growing
natives which has seemed so successful for Don Burke.

Basic idea is to mound sandstone rubble to 1m add 10 cm compost with 10
cm mulch. Plant natives directly into sandstone and stand back.
So to do this I need to source cheap sandstone rubble. Apparently you
can get it cheap from quarries as it isn't very useful for any thing
else.
I'm in Sydney north west. Anyone had a go at this? Where do you get the
sandstone?

Sandstone rubble is still very cheap, but the cartage is a killer. I had
trouble getting it at a decent price because I live at Lidcombe -- you may
have a wider selection because of your location. I just used the Yellow Pages
and settled on Bakers Landscape Supplies. Last March, they charged me $200
for 10 tons of 10cm sandstone rubble. I need a bit more, actually.

BTW, you can skip the compost, and use much less mulch. I am waiting for my
council to drop off tree chippings and am making do with a light cover of lawn
clippings. Even the Boronia megastigma has coped with the heat so far.

I used the John Hunt technique of having a 50cm deep 50cm wide trench dug in
my clay soil as a water reservoir (it's got brickbats and broken concrete in
it as well as the rubble). He reckons this works better than just mounding
soil up. It appears to be working -- I'll get back to you in ten years!
