The book details much of the history and nature of Victoria in Australia, including I was pleasantly surprised the Eureka Stockade, the scene of a heroic rebellion in 1854 from which we get the Eureka banner, similar to Irish banners, based on star constellations. Professor Geoffrey Blainey said the Eureka flag was an "Irish Cross."
Wikipedia says of Frank Hurley:
From the same source, re. Shackleton's explorations:James Francis "Frank" Hurley, OBE (15 October 1885 – 16 January 1962) was an Australian photographer and adventurer. He participated in a number of expeditions to Antarctica and served as an official photographer with Australian forces during both world wars.
He later compiled his records into the documentary film South in 1919. His footage was also used in the 2001 IMAX film Shackleton's Antarctic Adventure.Links:
