The Australian Arid Lands Botanic Garden is well worth a visit if you are in the area, we enjoyed a walk through the more formal landscaped part.
We also walked a little way along the bank of the Spencer Gulf, we saw our first live kangaroo of the trip
and the mangrove forest on the waters edge
On the way out we encountered a handsome lizard, it seemed quite big to us, the white line in the second photo is 5cm wide.
