Mr TURNBULL (Wentworth—Prime Minister) (14:50): I cannot give the honourable member confirmation about the exact percentage, but there is no doubt that wholesale electricity prices have considerably increased in very recent times. There is no doubt about that, and the major cause of that has been the increase in the price of gas. The wholesale price of gas has risen dramatically. That has been in large part because of the policy decisions taken by state governments, in particular the state government of Victoria, which has banned the exploration and development of gas. Mr Hammond interjecting— The SPEAKER: The member for Perth is warned! Mr TURNBULL: We are taking decisive action, including the potential restriction on exports of gas—very stern measures—to ensure that the east coast domestic gas market is fully supplied. We are taking those actions to do that, and that is our response to ensure that we bring gas prices down. As I said earlier in response to a question, I think from the member for Port Adelaide, the measures already announced have had a response, but in the time available I will ask the minister to add to my answer.
