OZ currently fly two types of planes to SYD, A330-300 and B777-200. I think both still have only angled-flat beds in J.
I haven't flown either of them in business class however however if you can get to choose first class, here's my review of both OZ and KE:-

Looking at the photos, OZ F lounge looks very similar to their J lounge. I hope it's better because I thought the J lounge was a bit boring.
