To hook in on that though. Just like in any multiplayer environment, the positioning of another player on your screen does not just depend on your own latency with the server. But is also dependent of the latency of the other player. So even if you live very close to the server, you'll still see other players lagging behind. The only solution to that would be to have every single player live within close proximity of the server, or for our internet connections to no longer travel by close to the speed of light, but actually teleport from one point to another.
And although researchers have proven to be able to teleport data at 10 kbit per second over a 6mm distance last year, we're still years away from any practical application there.
It's for that very same reason that in games such as e.g. counterstrike it was very common for players with 80 ms or over to be booted. As in a competitive environment their off-positioning was troublesome and posed a possible advantage. However, in an MMO none of that matters. It also doesn't matter which MMO you play. It's all the same. No matter what MMO you pick. Other players will always lag behind. The severity of it depends on how close you and your fellow players are both away from the servers.
I have no doubt that at some point you can start moving pre-emptively yes. Just to ensure that your movement data is picked up by the server in a timely fashion. However, bear in mind that the Australian player base is a very exceptional one. It's nigh impossible for any MMO company to account for that. Your country lacks the population to realistically sustain the population for most MMO's.
I do believe though that I recall to have read not too long ago that a series of fiber optic connections are to be laid out in the upcoming years between your continent and the southeast Asian territories. Probably reducing your ping to those areas to < 100 ms. Making it likely that in the future global MMO's with SEA data centers may be more likely to open up Aus servers there.
