One thing Richard, is you have to be careful, I am not sure where Tolga Australia is, but I imagine you are in a temperate region/climate and Shawn and the rest of us are in Tropical climates, so when it comes to humidity, etc. or lack of additional precautions about humidity, be careful, you might have a way more drier and cooler climate than we do.
That said, even in tropical climate like Shawn's Kho Samui, he has this nice automatic mysting system. I don't have those, and even though relatively humid in my area, I do still put some of my cuttings in a humidity bag or something I use 2 liter pet bottles (softdrink) cut to make a tall humidity dome.
