Hope this info helps

The girders are made from steel (79% imported from England and 21% from Australian sources). The pylons are made of concrete faced in granite, which was quarried near Moruya, 300km from Sydney. Around 6 million rivets and 52,800 tonnes of steelwork and 17,000 cubic metres of granite have gone into the construction of the Bridge. The bridge took 8 years to build.
