Photo 3 is not of cones. I suspect it might be galls. I have checked in Lindsay Prior’s book ‘Trees and Shrubs in Canberra’ published 1991. This species, Cupressus macrocarpa as it was then, was not on the list for the streets that Clarrie Hermes Park abuts on. So I suspect it was planted post 1990 or so.
Photo 3 is of a seed cone. Records of trees planted in Hughes in the early days are sometimes a bit inaccurate. Thanks for sorting it out, the trees have an ancient look about them!
