In my former home we had an abandoned over-grown market garden over the back fence. One day the authorities decided to burn it off because it was a fire hazard.
A few days later I heard a noise in my kitchen and I went out to investigate and two bandicoots ran past me. They had been eating a piece of bread that been dropped on the floor.
This was before I had any cats so I started to leave out diced apples, and rolled oats mixed with peanut butter for them. I rarely saw them but the food was gone each day. I kept doing this until there was regrowth over the back fence.
I also found an echidna in my yard once. As soon as he saw me he dug down into the ground so I left him alone.
