Shows fish going up a fish ladder (or fishway) on Wolli Creek in inner south-west Sydney. The fishladder was constructed in early 2009, ending a situation where, for decades, it was almost impossible for native fish to navigate between the salt and fresh sections of the creek. An example of a simple device making a big difference to a degraded ecosystem.
