Senator CASH (Western Australia) (14:24): My question is to the Minister representing the Minister for Immigration and Citizenship, Senator Lundy. I refer to the fact that the Department of Immigration and Citizenship now costs more than $1 billion a year more to run than it did when the Howard government left office— Government senators interjecting— The PRESIDENT: Order! I need to hear Senator Cash. She is entitled to be heard in silence. Senator Cameron interjecting— Senator CASH: Doug, get back in your box. The PRESIDENT: Order! Senator Cash, ignore the interjections. When there is silence we will proceed. Senator CASH: and that officials have attributed this blow-out to the increase in boat arrivals. Given that more than 15,000 people—including 1,221 so far this year—have now arrived on unlawful boats since the government's decision to abolish the border protection policies of the Howard government, does the government agree that former Prime Minister Rudd was wrong to abolish the Howard government's proven border protection measures, which reduced the number of boats coming to Australia to zero?
