Looks all Gold to me; however, if you are curious there are DNA tests you can do. If it is available in Australia I'd recommend one called a Wisdom Panel done with a blood draw at your veterinarians/ It seems to test for more breeds and was more reliable. We had to do the cheek swab one twice. When the blood dna profile came out we did that one as well. In both instances they came back all golden, even though our older guy sports a very curly coat, longer snout and some interesting howling behavior.
