A lot of people do tend to be lucky at finding the right PUG raid group, but also just got to be patient and keep searching for the right guild for you. The guild that I am a member of has 4 raid teams, but we also run social raids on a Friday and a Saturday to run the new and old content and is open to virtually any member to signup and experience the raid zones and give people the opportunity at grabbing some loot. Not every guild will have that, but quite a few do, just need to find the one that will suit you the best, which will be doubly hard as a aussie i will admit.
