Feeding native wildlife
They say don't feed the native wildlife so they won't become dependant on humans and then forget how to find their own food in the wild. This is fair enough for kangaroos, marsupials etc. However, I reckon feeding the cockies is ok.
Also watch out for the kangaroos who might get a little aggressive with you if you have food, I have heard more than one story of a person being attacked or even having with body cut open up the middle when a kangaroo wanted some food. Zumsteins is particularly 'notorous' for this, as there are many many kangaroos here. So just watch out.
