Limited in several ways: total bandwidth, independence, number of routes, and latency.
Australia is a long way from anywhere. It's closest technical neighbor is NZ, but by several measures, that's tiny. Among the benefits AU has is that it's relatively close to India and the Philippines, both of which share a fair bit of language and culture (Commonwealth / US protectorate).
Both are countries with their own distinctive histories and cultures, tough they share a pretty significant colonial history under an English-speaking power (England, for India, the US for the Philippines), resulting in a population that's largely English-speaking. At least among educated classes. As opposed, say, to most of the rest of Asia. Yes, China was some English dominion, but other than Hong Kong the legacy isn't particularly deep. Japan's largely been independent (though with some US influence post WWII). Vietnam some French/US influence, but it's not a significant tech player.
Australia from my time there is very much a crossroads of Asian and the Pacific. Especially Sydney. But I see stronger cultural ties with these two countries in particular.
So, yes, for countries which are technically relatively forward in its hemisphere, India and the Philippines offer some cultural landmarks offering commonality.
