Can I access any SQ (or Star lounge (I'm Star Gold)) before my flight to Yangon by virtue of the fact I have a same day SQ flight?

My experience is limited to Qantas where, for example, I would be able to access the QF lounge prior to the flight to Yangon, irrespective of the airline I'm flying with to Yangon, if I was flying with QF that same day.

If you show the boarding pass for sin-lhr then yes.

But otherswise ymmv: if you are lucky: I have been granted access to sq f lounge on arrivals sq f then departing sq biZ. I have also been granted access to sq private lounge on award tickets.
