Victorian voters heading to the polls will probably get a taste of the evidence heard by a royal commission – including how taxpayer funds were used on Big Build projects – but it could actually help Labor’s standing, an integrity expert says. Shortly after being sworn in on Tuesday, Carroll said the creation of a royal commission into the construction sector would be his “first action” as premier. This follows sustained pressure to investigate alleged corruption on the government’s Big Build infrastructure projects. Carroll also said a special prosecutor would be appointed to work in parallel to the royal commission, and that the Independent Broad-based Anti-corruption Commission will be bolstered with follow-the-money powers. Partlett told Guardian Australia the decision to hold a royal commission was not surprising, given the pressure the former premier was under from the Labor caucus over the issue.
