Yep! There's a CX lounge in T2 (07:15 to 18:00) you should be able to access as well.
There's also an EK lounge (also T2), but it has short operating hours (18:00 to 22:00). You should have access to the EK lounge on the basis of QF Gold + QF flight number (but depending on the time of your flight, not sure if worth, I've never been myself).
