You can try iVet if you are in Darwin or VetChat if you are elsewhere in Australia

For small cuts and grazes that don't need veterinary attention, you can apply some antiseptic a thin smear of Savlon® cream which you are able to get this from any woolworths store, as recommended by this Vet:

Otherwise you are also able to use a teaspoon of salt in 600 ML of warm water.  You should apply the salt water or Savlon cream every few hours and also dress the wound in a small amount of bandage and tape.
