PvE: Looking for Aussie players

Hi I'm looking for a guild to join after being away from the game for over a year. I'm from Australia and would preferably like to find some players also from Aus. That said, any helpful guild would be welcome
People who can help explain some of the changes to the game since I've been gone would be awesome as I'm looking to return on a casual basis to fit in around work/social life.
Would mainly be looking to go after titles or HoM things i suppose.
Thanks for your time,
Sarah
