Thanks, here's a further proposed patch (also out on github)
to try to deal with this.  I'd like to generate a new release
soon, hope this is the last substantive patch but will give it
a day or so to percolate....

Subject: [PATCH] Fix times of habitation for Macquarie to agree with Tasmania
 history.

Also, sort Macquarie more-consistently with other parts of Australia.
This doesn't affect time stamps, just zone selection.
Problems reported by Tim Parenti in
<http://mm.icann.org/pipermail/tz/2013-April/019060.html>.
* australasia (Antarctica/Macquarie): Tasmania Parks & Wildlife Service
history indicates that permanent habitation was 1899-1918 and 1948 on.
* zone.tab (Antarctica/Macquarie): Move next to Lord Howe and Tasmania.
