The Hunter River is the lifeblood of the Hunter Valley. But since early settlement it hasn't been treated like a life blood; it has been exploited, turned into a dumping ground and over-run by weeds. In 2001, ABC Newcastle's Phil Ashley-Brown interviewed people along the 470km Hunter River between Barrington Tops and Newcastle Harbour. In 2003 the series highlighted the poor state of the waterway and tapped into a passion that many people have for the Hunter River. In 2011 Phil went back to the river to see how much change there has been over the last 10 years.
