"Goodbye Blinky Bill" is a song written and recorded by John Williamson with Bullamakanka and John’s daughters Ami and Georgie.

The song was released in a limited edition in March 1986 as the only single from Williamson's 1986 compilation album All the Best.

The song is a conservation song, raising awareness of the decline in numbers of the Australian koala due to deforestation of eucalypts trees; with reference to an anthropomorphic koala named Blinky Bill.

A$1 from each sale was donated to the Koala Preservation Society in Port Macquarie.
