Both countries experienced ongoing internal conflict concerning indigenous and settler populations, although this conflict took very different forms most sharply manifested in the New Zealand Wars and Australian frontier wars respectively. Whereas Maori iwi endured the Musket Wars of the period 1807–1839 preceding the former in New Zealand, indigenous Australians have no comparable period of the experience of warfare amongst each other employing European-introduced modern weaponry either before or after their own confrontations with European settler society. Both countries experienced nineteenth century gold rushes and during the nineteenth century there was extensive trade and travel between the colonies.
