Senator MUIR (Victoria) (14:42): Mr President, I ask a further supplementary question. The renewable energy industry has faced enough uncertainty in recent times. Despite reaching an in-principle agreement with the opposition, the announcement by the government that it will conduct two-yearly reviews has revived this uncertainty. Can the minister confirm whether the government would proceed with two-yearly reviews of the renewable energy target or whether it will consider conducting its first review in 2020 in order to provide some real certainty to the sector?
