The elderly women told media outlets the wombat was wandering around her property, 75 kilometres from Dubbo, and onto her verandah in an attempt to get inside her house when it attacked her.

She sustained injuries to her leg and her hand in her attempt to restrain the wombat from running towards an 11-year-old who was also at the scene.

WIRES spokesperson Tanya O'Donoghue said wild animals normally won't wander into human spaces in an attempt to gain access inside a house unless they've been encouraged with food.

"We say not to feed them because they not only become reliant on that food, they can become dangerous when demanding to be fed," she said.

"They are wild. They can't be `trained' like domestic animals to wait to be fed. When you start feeding them you blur the boundaries between yourself and them.

"The other thing I can't emphasise enough is do not approach them.

"Most of our wildlife are prey animals. They identify us as a predator. As soon as we start to approach them they will feel threatened. Their `fight and flight' instincts will kick in right away. They feel their life is threatened. That's what they are conditioned to feel."

Ms O'Donoghue encourages residents to be respectful and give wildlife space.

It is understood the wombat involved in Wednesday's incident was hit with an axe in self-defence and died at the scene.

Ms O'Donoghue is also encouraging the general public to start educating themselves in an attempt to understand wildlife a little better as to avoid horrific situations.
