Further to Karl Miller's work list for Williamson:

The Display is a ballet (about 25') concerned with the courting ritual of
the lyrebird, a magnificent Australian species which is also a superb mimic
- see David Attenborough's The Life of Birds (BBC/PBS, depending on where
you live, being shown in Australia at the moment).  The recording (late
60s, IIRC) has not been silvered.

I have heard his Santiago de Espada Overture and Symphony #6, the
recording of which has a movement played by each of the six Australian
state orchestras, as the composer intended.  As far as I know, both
were in-house recordings by the Australian Broadcasting Corporation
(http://www.abc.net.au/) which has its own CM labels.
