I talk about "big" map, not huge, the second one in size.
Large. Even on Large Australia is a little isolated.

Polynesia should be made to start there now.
It would be more accurate to have Polynesia start in Hawaii (their capital is Honolulu) or New Zealand (Their unique unit is the Maori Warrior and Maoris are New Zealand's native people).
Technologically speaking the Australian Aboriginals were the most primitive people on Earth when Europeans made contact. They lived nomadically, were stuck in the Paleolithic (stone age before inventing agriculture) and even then used wood for most of their tools. This isn't exactly their fault - Australia had no native plants that could be turned into crops, and no native animals that were suitable for domestication (even Dingoes migrated from SE Asia). The people in New Guinea (a far cry even from the Indonesians just to Australia's north who had benefitted from technology and cultural influence from the middle east to china) at the very least farmed yams.
This is not to mention that even given how far away from the rest of the world Australia is and that it had poor soils, and no native animals or plants suitable for farming - the sides of Australia closest to Asia and Africa - that may just have possibly been visited by outsiders, were the crap parts. Thousands of miles of western and north coastline which is either desert, cliffs, swamps and dry tropical scrub/forest.
It's the same reason civilization as we know it didn't penetrate through the saharan desert, dry african savannah, tropical jungles/swamps and more savannah and desert to reach peoples like the Zulu until so recently. Because seriously, that.
Australia's best side - the fertile east coast - was almost all forest and facing the incredibly huge pacific ocean. The same ocean it took the polynesians millennia to colonize. The first humans stepped foot on New Zealand only 700 years ago or so. (Then the British came 500 years after that).
My main point is that apart from maybe some amazonian tribes, or tribes in the african rainforest, australians were the world's least technologically advanced people and it feels weird enough having Native American civs (who in civ terms had invented agriculture, mining, trapping, pottery, animal husbandry, archery, skipped the wheel gone straight to horseback riding) and Zulus (agriculture, mining, pottery, skipped bronze working to iron working, animal husbandry, masonry, trapping) and Polynesians. Who together are historically the least advanced of the civ 5 races.
