Rabbits were introduced to Australia in the 1800s by British settlers for food and hunting. A man named Thomas Austin released 24 rabbits on his property which then rapidly expanded across the country. By 1900, rabbits had reached all states and caused significant environmental damage by overgrazing vegetation and preventing regeneration. Their populations were controlled through methods such as fumigation and diseases like myxomatosis, but rabbits remained a major pest. Further extermination efforts are needed to eradicate feral rabbits in Australia.
