Through that intervening 300 million years, it has changed dramatically. The last period of glaciation was 12,000 years ago, when Sydney Harbour was a river valley. It was carved by glaciers at that time. When people think about climate change and rising ocean levels - at that time the ocean was 120 metres lower than it is today.
