Just started listening to a band called Psycroptic, they released an album called Ob(Servant) in 2008 and have a couple of older albums that I haven't checked out yet. They fall into the technical death metal category and are from Australia.
Ob(Servant) is a solid album. Complex riffs, brutal drums. There is some variety in the vocals, despite being death metal. Everything is very tight.
Here is a song called "Slaves of Nil"
