Thanks, Andi. The beach I found this on/under used to be a fishing village from the early part of Australia's settlement. Captain Cook first came into Botany Bay in 1770, the First Fleet arrived 1788 and a few decades after that the area was known as Booralee Fishing Village. Tanneries and wool wash industries thrived in the area, so perhaps my metal finds were something to do with these industries. I just like the look, shape and feel of them and I'm dead curious about what they are. I've tried cleaning the metal to see if I could get a shine but the colour in the picture above is how it was found and how it will stay.
