These men (including "Mac" Williams lower left), are also in the previous photo, this time loading up the Francois with what look like goat carcasses. My father was a handy man with a rifle. Was there an island in Moreton Bay where goats could be hunted in the late 1920's to early 1930's? And who are these men?
Could the two on the far right be Dick and Ricky Watts?
