The Opera Theatre, seating 1,547, is mainly used for performances of
opera, ballet and dance. The auditorium, like the Concert Hall, is
panelled in wood for acoustic reasons, but the ceiling and walls are painted black to allow the audience to focus its attention upon the
stage. The proscenium opening is 12 metres (38 feet) wide and 7 metres
(24 feet) high and the stage extends back 25 metres (82 feet). Built into the stage floor is a revolve 14 metres (46 feet) in diameter and
there are four platform lifts 10.5 by 3.5 metres (35 by 12 eet) which
raise and lower the scenery between the set storage area at ground level and the stage 10 metres (33 feet) above. The orchestra pit can
accommodate up to 75 musicians.
The stage curtain is a tapestry designed by the Australian artist
John Coburn and is woven from Australian wood at a factory near Aubusson
in France. Of abstract patterns in bright warm colours it is known as the Curtain of the Sun.
The Drama Theatre
The Drama Theatre accommodates performances of drama and dance. It
seats 544. This auditorium, like the Opera Theatre, is black but the
rather low ceiling is made of refrigerated aluminium panels which help to create an even temperature without a draught. The
stage, which is about 15 metres (52 feet) square, contains two revolves,
one inside the other, which can turn separately or together. The stage curtain, also designed by John Coburn, is similar to that in
the Opera Theatre but is woven in dark colours. It is known as the
Curtain of the Moon.
