[5] In August 2011 it was reported in News Limited media that the Department of Finance had sought reimbursement from Edwards over the misuse of three government-funded cars.

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.

[11] 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 7 April 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-principle support for covering the capital costs of deploying new nuclear technology.
