you need to check with the ATO what is classified as income when it comes to inheritance, capital gains etc.

i "think" the only thing that happens is, if you invest, the income from interest (with inheritance or sale of a house more htan a year old) - but capital gains makes it all different. unfortunately we just have to run with what ATO says is income and we dont get a lot more training than that (nor do we really want it! too much info to know as it is!)
