I am based in SIN and have been for almost 17 years (originally from Melbourne). I have zero business travel back to Australia, so it is all leisure/VFR. Since covid finished, I've definitely moved to day flights (a ratio of 5:1 daytime to overnight),
But I don't sleep well on planes, even in business, and for most of that time I most people I dealt with were in Europe or the Americas, so arriving in MEL at 8-9pm (5-6am on US east coast) proves to be less disruptive than departing SIN at 8-9pm...
