Second thoughts are sometimes better thoughts. The NSW government had second thoughts about closing down the Powerhouse Museum at Ultimo last July prior to its removal to Parramatta to premises not yet built. It is apparently a permanent reprieve; there are to be two Museum campuses. So it is pleasing to read the announcement of the Museum’s program for 12 new exhibitions at Ultimo drawn from the collection that holds more than half a million objects of which scarcely 10 per cent have been seen by the public.
