Great question. I still live very much in the past for music. Love old school Silverchair. Bit of Grinspoon/Powderfinger doesn't hurt either. Wolfmother's debut album is almost perfection. Airbourne, Rose Tattoo and AC/DC for hard rock.
Recent stuff I like, and quite a change in my musical tastes, would be bands like The Rubens and Flight Facilities, but I haven't heard more than a couple of songs from either.
