London dominant right now (but doing very little) it's basically around the clock, around the world (commodities and currencies), but obviously less liquid if US markets are Closed.
NY traders (on the CME) are unquestionably the big dogs...the rest is nickel and dime stuff (most especially, Asia / Pac Region).
If you had an account, you could trade it right now (probably as a CFD in Australia).
I don't , but am increasingly attracted back to commodities and currencies...I did trade them on CME some 15 years ago living and working in NY.
