As for international - it depends on the route but the competition (SQ, CX, MH, TG) already has better J class seats and cabins than the QFi A330s, and the competition will have lots of younger A330s, B787s, B777s etc
Worse than TG? I must have been dreaming last time I flew TG business class, SYD-BKK-SYD. On the way out it was a 747 with a seat not too different from what Qantas has on their A330's. Appart from the colour I couldn't really tell you the difference. On the way back it was a sit-up recliner seat. Now yes I know the sit-up seat was not meant to happen, but it did. Other than that though what TG offers on flights to Aus, is their long haul product, which is not too dissimilar to what Qantas has on the A330's. Angled bed, same basic seat design.
As for SQ, they operate regional business class a/c to Aus with with a seat not too different to current Qantas A330 J seat. Now yes it looks different, but is not 100% lie flat, and has the same size same basic idea in design and layout.
Found on A330's, which yes are newer than Qantas's, these operate to Brisbane, 2 a day to Perth, Adelaide and 1 flight to Melbourne. SQ also fly the older 777-300 and 777-200 on flights to Sydney, which are a mix of seats similar to their A330's and recliner, though not sure if they fly recliner fitted a/c to Australia.
A380 and 777-300ER, yes much better than Qantas A330, though this is a long haul product only operates to Syd and Mel, but not all flights.
MH, again new A330's with a seat not too far removed from the current Qantas seat (closer in look to SQ's), plus some older 777's, again similar seat (closer in look to QF). Neither lie flat either, same basic config.
CX regional business class is a sit-up seat, though of course they don't fly them to Australia, but instead fly long haul fitted a/c, which on the new config is about the same as QF A330 business class.
So really I would say if you exclude the long haul competition, what Qantas runs now is on par with most, and what they will be running will put them on top.
As others have pointed out - the A330 J refit is welcome but it is really only catching QF up to where the competition has already been - not where the competition will be by 2014....
See above and happy to hear what new product the competition are planning in the next year or so.
