Six flights daily when you include the ones that go on (one to HKG as well as this one to SYD) EK370, 372, 374, 376, 384 and 418 are the outbounds. They also seem to chop and change between B777 and A380, 2 class and 3 class a lot, perhaps seasonally. Same as the OP, I'm on EK418 soon and was surprised to see it was a B777, but I've got 7J so happy enough with that.
