Interestingly, the appropriate QF page (linked to above) still indicates the JL Sakura Lounge is the Qantas Club access for lounges, but my last departure mid-2010 on QF I proceeded to the BA Terraces lounge. The BA Terraces Firstl loungelette / closet is small and not extraordinary comfortable - one time Lady JDiver and I used it, Christiane Amanpour (CNN) was there - and we all soon departed for the more spacious Business lounge.
