Yes. One person I know left there boots outside the tent.. took some hours to find one boot the next morning .. obvious teeth marks and saliva on it - a dingo. Keep all your gear in the tent or out of pilfering range. Dingos do recognise water bottles too.
I have had a dingo look in my tent, it was open. Another person noticed and shooed them away. Keep your tent closed.
The animals are not aggressive, yet, as no one feeds them so they don't demand food from you and if they fail to get it came after you. Message .. do not personally feed any of the animals! But they do see your gear as a potential source of food and water. So they will look if given the chance. They will even track you to see if anything falls off.
I think the lockers are for mice/rats at that location.
I have had mice/rats chew a hole in a canvas bag to try and get at food. They have very sharp teeth.
