I wonder if this helps explain why Australians are ditching QF intl for other airlines.
It was probably the major reason why I ditched QFi. BA being just as bad space-wise didn't help, and all in all has led me to ditch OW. I don't have a choice to travel other than in Y. I used to get free exit rows just for asking (I'm tall). But QF and BA have charged extra for them for a while now, which has strangely created a demand amongst pax who are not tall (and often not emergency-fit). It became hard to get them even when paying.
Other airlines still give me exit rows for free. But as your list shows, even the mostly Asian airlines I now fly with have more spacious regular seats, despite having the smallest pax !
There was a long list of other things that turned me off QF, but lack of longhaul comfort was right up there. My knees are much happier.
