Would be pointless for Dick to be in the House of Reps in my view. His opinion on anything would be ridiculed by the major parties unless it was a hung parliament,and only then because they need his vote. Senate would be similar but a better chance of being minority government held chamber.
Really though Dick had his chance to change things when he headed up the then CAA years ago. If I recall correctly he got frustrated with it all and quit,which I suspect he would do as a politician.
Time to move on,his day has come and gone.
