There are a lot of underground streams in Manhattan, but there are no ground-level rivers that run through Manhattan, no. Around it, yes, but through it, no. The Bronx is the only New York City borough that has a river running through it (the Bronx River).
The Murray and Darling Rivers of Australia are two separate and distinct rivers. The Darling does not flow through any cities. The only "cities" that the Murray flows through is Albury-Wodonga and Murray Bridge. There are numerous large towns along the Murray, and fewer along the Darling.
