Melbourne and the Yarra River.

The Yarra River is not big by world standards. It runs for just 242 kilometres from its source on the flanks of Mt Baw Baw in the Yarra Ranges National Park to its mouth at the head of Port Phillip Bay in Newport.

It is not very long, very wide, nor very deep. It is not even very clear. But this sepia-coloured river has had a big impact on shaping Melbourne – the city that grew up on its banks.
