Wow! Looks like A River Somewhere is not available on any streaming services in the world!

A River Somewhere was an Australian documentary television series originally broadcast by ABC TV in 1997 and 1998. It was produced by Working Dog Productions, and was hosted by Tom Gleisner and Rob Sitch. The series was released on DVD in 2005. The series focused on the observations of Sitch and Gleisner as they travelled to various locations across Australia, New Zealand and around the world to fly fish and experience the local culture. The aim of their expedition was to "catch dinner and have it cooked in a local style". The music used throughout the series was created by Australian musician and composer Liam Bradley.
