Great report!
Living in Perth, so brings back fond memories of my (then) teenage son and I flying this route on the way back from Europe a few times and lounging in the bar with the red roses insert in our pj's before landing - now its more of "I might fit you in for a weeks trip in 2024 Dad" !!
I recall the bathrooms and the bed in F being better than J and not infrequently, the food (with the exception of the caviar) I requested from the J menu being better. There was also the small mater of that half bottle of Chateau d'Yquem that no one seemed to want to share 😁
