Terri Irwin, wife of the late Australian environmentalist Steve Irwin, bought 33,000 acres of adjoining land in 2015 and added it to Mourachan, a conservation property in Queensland. The property now covers 117,174 acres and is home to the endangered Queensland subspecies of the woma python, and koalas. Terri also planted 44,000 eucalyptus trees on the land with her father.
