Ping and Account recovery question

Hi, I'm a returning player and I was just wondering if anyone here plays from Australia? What's the ping like? The main reason I left the official NA server was because my ping would be between 400-1200 (averaging around 600ping) and that amount was just unplayable for me. Where are the servers located? I live in Sydney Aust, which server would be best for me to connect to? Is the ping any better then the NA official servers?

Also something a lil unrelated, I was wondering where/how I can...
