A couple suggestions.

[Slayer]

If I remember correctly, many Australians have asked hyper if they can pay for an Australian server themselves of the $20/month and understand that they do not own the server, they cannot do what they want blah blah blah, and they have been rejected.

So from my understanding, it is not possible for Australians to willingly pay for their own servers.

As for the people saying Australia is low populated, this is so untrue. The Au servers are populated for 12 hours straight most of the time. I wake up at 2 PM and go to bed at 6 AM most nights, I go into teamspeak, guys say they've been playing on AU since 8 AM. Coming about midnight, we leave the NA/EU servers and say bugger this, fed up of wiping, we pop over to an AU hard server coming midnight and theres about 10 of us and around 6 EU/NA player who pretty much complain about high ping.

So saying that the AU community is not active is a lie. Anyhow, I am an Australian who stays up during prime EU time and I can tell you now that not even on weekends are all the EU servers full, let alone NA.

But as already stated, they're in a single box and taking 1 or 2 servers out would change nothing.
