It is an interesting idea to have eminent Australians participate in parliament debates. Equally, the same effects could be achieved with an effective forum for eminent Australians to voice their opinions and inform the parliament. The only reform needed is for the parliament to note and debate recommended opinions by the forum. Such a forum could also include creative opinions of other Australians.
