Senator BIRMINGHAM (South Australia—Minister for Education and Training and Manager of Government Business in the Senate) (14:24): I thank Senator Martin for his question, which may be his first question. Indeed, I acknowledge his first question in the Australian Senate. Opposition senators interjecting— The PRESIDENT: Order on my left! Senator BIRMINGHAM: In relation to the issue of Commonwealth marine parks and particularly the economic impact, I'm happy to inform the senator that these plans are critically important for all marine users—commercial and recreational fishers, the dive industry, aquarium businesses and tourism operators. Compared to the previous Labor government's proposed plans, the coalition's plans halve the economic impact to commercial fishers, including, in the senator's home state of Tasmania, entities like Petuna Seafoods, which operates through Commonwealth waters along the east coast and beyond and employs some 264 people. Our management plans for Australian marine parks give them certainty over their fishing grounds— Senator Pratt interjecting— The PRESIDENT: Order on my left! Senator Pratt! Senator BIRMINGHAM: and ensure that a reputable, best-practice fishing business, like so many others across Australia, will get the certainty that it deserves. Opposition senators interjecting— The PRESIDENT: Senators Pratt and McAllister! Senator BIRMINGHAM: In addition to commercial fishing, these new management plans give greater recognition to the rights of some five million recreational fishers across Australia, individuals who support a wider economy around tackle and bait shops, as well as boating and charter fishing businesses. I note that tourism operators across the country have welcomed the mixed-use nature of our protections for the marine environment, which indeed still provide strong, robust protections. Ultimately, we hope this Senate gives the certainty to Australian marine operators that they deserve as well as the certainty of protection that the marine park plans we have laid in this place provide across our critical waterways. The PRESIDENT: Senator Martin, a supplementary question?
