Problem is that a Royal Commission would only be able to focus on any wrongdoing by the West Australian government in giving the money to Thiess not on what Thiess ( as a public company ) finished up doing with it. It seems that this should then have been dealt with by Thiess itself. From Hairyback's info it appears Thiess was not prepared to put in a complaint to the police.
I'm also not certain that the Workplace Minister has the power to investigate a union (as an entity), as the minister's focus is on employers and the workplace and only the union's role in the workplace. I'm happy to be corrected on this if I've got it wrong.
