Mushrooms?

I was just daydreaming about the additions I’d like to make to my garden over the next few weeks, and in addition to strawberries immediately coming to mind, I thought of mushrooms. Now, I’ve always wanted to grow some, but I don’t know where to get a good mushroom kit from.

If any of you lovely people have any idea of where I can get one from in Brisbane, I would be eternally grateful!
