Regarding in which region an island lies, a good approach is probably to
refer to the IHO (International Hydrographic Organisation) publication S-23
on the limits of oceans and seas. Unfortunately the current (1952) edition
removed the Antarctic or Southern Ocean as a separate region as it was
deemed to be an arbitrary delineation with no clear northern geographical
boundary. However work was done on a 4th Edition in 2000 which reinstated
the Southern Ocean and set the limits as 60 degrees South. This edition
would have been published and in force now, apart from a reservation from

So I would propose that any TZ data south of 60S, which means that Macquarie
Island does not fall in to Antarctica.

Organization into the top-level structure is by continent or oceanic region,
not by political entity.  Otherwise, it would be America/Honolulu, not
Pacific/Honolulu.  That's why Paul's reply pointed out the ambiguity of
geographic classification, rather than focusing on the political

Classifying by political entity is a fast way to get us into trouble in more
politically contentious places.  Consider Atlantic/Stanley, for example.

Australia is somewhat confusing in that context since it's both a political
entity and a continent.
