This is a Polypore Bracket Fungus, likely a Lietiporus Portentosus or Ryvardenia Cretacea, they can be difficult to tell apart, but both make excellent tinder & are worth collecting if you are getting low on tinder.
This is another Polypore Bracket Fungus that grows in the North, America & England I believe. This is Piptoporus Betulinus or Birch Polypore.
An Australian Native Bee hive in a dead tree (New England NSW). Honey is a good food, can be added to water & keeps for years, & it has antiseptic properties & can be used on open wounds.
These native bees have no sting.
Goonagurra/Grass Tree, Kangaroo Tail, or Yacca. There is a similar plant that grows in America known as Yucca. This Yacca plant cant be used for making spear shafts, you can suck on the nectar or put the flowers in water to make a tasty drink. Natives have been known to let this ferment to make an alcoholic drink. The ends of the leaves once pulled can be eaten & the sap can be used as a glue. When the flower stems have dried, the inner core makes good tinder. Dried leaves makes excellent light kindling.
