Not recommending QP membership, but just to correct the facts: you get international lounge access to all lounges that QF uses outside of Australia that are labeled "Qantas Club" (these include LAX, BKK and soon NRT, not 100% sure about HKG but I think QP does give admission to this joint QF/BA lounge. Also get access to AA lounges when flying AA, and BA lounges when flying BA (so about 100 additional lounges). But for a single trip it is much cheaper to buy day passes at the airport (many lounges sell passes for circa USD50 per day, though the better ones do not). At HKG there are at least 2 options for bought lounges and showers, check the airport web site. Similarly at HEL. Or buy Priority Pass, which has lots of different airline lounges (not that I am recommending that, either).
