Senator HUME (Victoria—Minister for Superannuation, Financial Services and the Digital Economy and Minister for Women's Economic Security) (14:22): Senator Whish-Wilson, thank you very much for your question. Hand on heart, Australia is a good citizen in the world heritage system. We have implemented all previous recommendations. But what on earth could we possibly implement on our own as a corrective measure to address global warming? We are delivering on all of our outcomes that we have committed to in the reef 2050 plan. That includes controlling outbreaks of the crown-of-thorn starfish, which eats coral; improving water quality; doubling the on-ground joint field management program; addressing plastic pollution; rehabilitating island, coastal and reef habitats; and, as reported in the 2019 Reef Water Quality Report Card, we are over halfway to the fine-sediment target and almost halfway to the dissolved inorganic nitrogen target. I reiterate that the Morrison government is deeply committed to protecting the world heritage listed Great Barrier Reef. Honourable senators interjecting— The PRESIDENT: Order. The wearing of masks makes it difficult to call senators to order because I can't see their mouths move, particularly at the rear of the chamber. I can recognise some voices at the front of the chamber.
