The Australian server gives slower responses, it's physically located in Australia. You probably won't be able get faster than 0.5 seconds as it actually takes around 425 ms to get a response from Betfair's server on my PC and I imagine this is pretty much the same for everyone else. When you select a faster refresh rate you are just sending more requests that won't get a response in time.
