Executive Council. As Minister for Sustainability, Environment, Water, Population and Communities, Burke established the Commonwealth Marine Reserve Network, the largest network of marine protected areas anywhere in the World and the world's second largest conservation determination after the preservation of Antarctica. Burke also added koalas to the threatened species list in Queensland, NSW and the ACT. He also placed a ban on a controversial Dutch "super trawler" fishing vessel operating in waters off Tasmania.

Following the June 2013 Labor leadership spill, which saw Gillard lose the Labor leadership, Rudd rejected Burke's offer to resign from the ministry. Burke, a Gillard supporter, had been critical of Rudd's performance during his previous tenure. Rudd subsequently appointed Burke as Minister for Immigration, Multicultural Affairs and Citizenship in the Second Rudd Ministry. In this role he oversaw Rudd's resettlement plans with Papua New Guinea and Nauru, which saw an immediate and dramatic reduction in
