Little Desert Nature Lodge (near Nhill in Victoria) - 21.82 (once Venus set)

On Tuesday night we had 20.6 with SQM (not the L version), around 10:30 PM at the Johns Hill Reserve, Ridge Rd. Kallista in Melbourne east. Venus was still up.
Only two scopes there a 12" Dobson and a 4" Apo, was a good night.

30 minutes from the outskirts of Haifa, but still close to various villages - 19.8 It's the "darkest" spot on the light pollution map close to Haifa.

My experience in Tibet, never reach 22th mag, at most 21.5 or so. Even at 5100m in the middle of nowhere, the closest real cities is 1000Km away, no light or air pollution, sky is crystal clear, at daytime you can see snow mountain >600Km away, or set of moon age 28th (Sun 30 degree above) by naked eye. I found the air is so thin there, the star light is brighter as not as attenuated as on sealevel, so interfere the SQM reading. Yes, at downtown of capital city Lhasa, I got ready approaching 20th Mag.
