I'm currently involved in two groups that may be suitable for you. One on Sundays in East Melbourne, the other on every second Thursday in Ripponlea (about to move to Kew). The former has a RuneQuest game which has more than a touch of horror involved, the latter goes through a few sessions of various indie games (recently WordPlay and Trail of Cthulhu).
Let me know if these interest you,
All the best,
