Mmkay. Decided to put this into perspective. Queensland is 715,309 square miles (total area- including water), according to Wikipedia. 3/4 of that is 536,481 square miles. That's roughly the size of Texas (268,580 sq. miles total), California (163,695 sq. miles total), and Colorado (104,093 sq. miles total). If we want to take water out of the equation, then it's like this. Queensland's total land area is 668,207 square miles. 3/4 of that is 501,155 square miles. That is roughly the land area of Texas (261,797 sq. miles), California (155,959 sq. miles), and Idaho (82,747 sq. miles). So, not much changes. But you get the picture.
