Why are monotremes found in austrillia?

Monotremes were among the earliest mammals to evolve. However, in most of the world, all monotremes went extinct as a result of competition with more advanced placental mammals. Australia and New Guinea, however, have been so isolated that there were nearly no placental mammals (except for bats) until humans introduced them. The lack of competition from placental mammals allowed monotremes to survive in Australia.
