Media outlets also reported that Edwards was being investigated by the Department of Finance over the employment, in his parliamentary office, of an executive of a company he chaired before entering parliament.
Edwards is an advocate for nuclear power in Australia. He believes that economic opportunities exist for his home-state of South Australia in spent nuclear fuel reprocessing and the use of Integral Fast Reactors to generate electricity. During a speech delivered to The Sydney Institute on April 7, 2015, Edwards said that he had worked on a business case for the expansion of nuclear industries in SA for around two years. He told the audience that he had commenced discussions with an unnamed foreign state which expressed in-principal support for covering the capital costs of deploying new nuclear technology. Edwards said that discussions on the matter had advanced to "a ministerial level". He has also attacked the Australian Greens for maintaining their opposition to nuclear power. In the Australian Parliament, Edwards has voted very strongly in support of uranium export.
