Understand the issues at some Australian Airports re Domestic & International terminals but Adelaide & Melbourne aren’t too bad to get to the domestic lounges .. 

Have to agree I think Darwin - Singapore with Qantas is still a good option if you are after points & SC , I also am not intending to fly on the 737 Max ,, Im sure they are safe but I will fly Qantas on this leg

An interesting discussion and varying viewpoints . I will own up to the fact I am primarily a Qantas Traveller and despite the problems post COVID I have stayed with them more out of convenience & their extensive network. I have found Virgin to be well priced when I have used them and service...

I have visited both QF lounges and found that both had their strengths as to do most of the others but I found the great staff at both lounges set them apart 

Like most here I rate the HK lounge very highly and definitely at the top percentage of Qantas lounges and also rates well against all HK lounges.
