There are a ton of products available that are basically little plant bits, mostly seeds. They look like autumn leaves. I don't know what brands or whatever are available in Australia. Some times it can be annoying trying to get these things shipped internationally because of laws on importing foreign plants/seeds. Customs agencies don't necessarily understand our little hobby. Snow flock = mysterious white powder, little baggies of static grass can look like like something you would want to light up and pass around, and yeah the little tiny seeds for ground scatter can violate laws for importing plants.
