In his introductory remarks about Clive Carey, and his time in Australia, Fahey mentions this:

"It should further be noted that the great English folk song and dance collector, Cecil Sharp, also chose Adelaide and spent some of his early years working in that city. Sharpe arrived in Adelaide in November 1882 and early in 1883 obtained a position as a clerk in the Commercial Bank of South Australia. He read some law, and in April 1884 became associate to the chief justice, Sir Samuel James Way. He held this position until 1889 when he resigned and gave his whole time to music."

I think I was vaguely aware that Sharp had been in Australia, but I had not made the connection in relation to this particular study. It looks like he was there for about seven years! That's a whole lot longer than he spent in the Southern Appalachian Mountains! Did he collect any songs in Australia and were any of them sea shanties? Where would one look to find out?
