One of the less publicized activities around here is Shroom picking. The Brindabella ranges tend to get absolutely capped with Mushrooms if there is a couple good days of rain followed by a couple days of sun.
And as fun as driving there and consuming every mushroom in site would be, it wouldn't be advisable as many of the mushrooms in the area and extremely toxic and you may very likely not have reception to call an ambulance as your liver fails and you die in a field of cowshit and mushrooms. However, if you know what you are doing, or you have a guide with you who can show you what is what, you'll be having fun in no time!
Some people have even returned from these mountains with garage bags full sometimes, if you find the right spots, and don't die after your first mushy, you're in for a good day.
