Funny how parochial we all are!
I wouldn't dream of suggesting that 1.25 hrs northwest of Sydney (where I am) is the best place!
Within commute distance of Sydney city and sky darkness good - especially west of the meridian.
Beware though Salva - the weather up and down the eastern seaboard has been terrible for the last 12 months because of La Nina - lucky to get 10% clear nights I reckon. When La Nina is not in play, or El Nino kicks in, clear nights are plentiful though!
