To be fair, a corporation had to raise a trillion dollars of capital and build that society from scratch before anyone else even seemed interested. How it progressed from that point to "the rest of Australia signed on" is entirely hand-waved away.

Just like real life, where nobody cares about programs like this and everyone refuses to help until they're already taking off. Which may or may not ever happen.
