As far as i know the only way to get a better ping is a high speed internet connection But keep in mind if you're in the US and the other person is in the UK for example your ping will be 200 or 300 because that is the time is take for the signal to arrive from the other end and vice versa.
anyway if you're looking for some player from Australia. try joinng the Ventrilo or TeamSpeak.
