On running for Grey: "It was a seed planted by the Liberal Party and look so I hadn't given it any thought until Nick Xenophon stuck up his hand and said he might run for the senate, he's my old boss, he gave me his seat, I'd find great difficulty in contesting Nick noting that he'd handed the reins to me, in those circumstances it would be highly likely I would switch to Grey ... but right now I want to represent South Australians right across SA"
The SA senator says he supports export of Grey's uranium deposits - to the right countries - but doesn't see a bright future for nuclear energy in Australia, saying renewable energy ought to have resolved its baseload energy generation concerns long before nuclear energy is viable for SA.
