i Have Internode btw its 2 mega bit per second constant... thats what my dad says.
the bandwith (size of upload/download) is not the important part regarding ping and does not mean "fast connection".
Ping shows the time the server in the Netherland needs to answer your requests and a good ping depends on how many stations (for example) you have to contact to reach the server finally and to get an answer.
From my experience players from Australia or US often dont have a good ping at european server because of the distance and No. of stations their data have to pass.
