can someone please tell me what make the yarra river unique?

Answer 1

The source of the Yarra river is a series of swamps in the upper reaches of the Yarra Ranges National Park, directly to the east of the Mt Baw Baw plateau, a thickly forested subalpine park, which is entirely closed-off to all except the employees of Melbourne Water. The park features extensive stands of mountain ash, a very tall eucalypt, tree ferns, as well as patches of remnant rainforest.
