G'day all,
Anderson's coast is about a convict escapee from Van Diemen's land or Tasmania, who is unable to leave the stretch of coast he has become marooned on. Based on the actual experiences of convicts around 1790's 1800's.
Re chords, there are no longer any official chords since I play it these days on 6 string, 12 string, bouzouki or unaccompanied.
Kim Poole's arrangement on Pithead In The Fern is DADEAB and is the setting that saved the song from obscurity. Kim showed me the DADEAB tuning which is how I play the 6 string most of the time.

Since the baby ran away from home with James Fagan and Nancy Kerr, she's dressed her self in a variety of costumes, so just enjoy yourselves and sing. John W
