If you'll allow me to share what I did, and it seemed to work...
QF 9 - SYD-MEL-SIN-LHR.
Flight departed SYD at 1300. Due at LHR at 0530 local. I'd slept until about 8am, arrived at airport at 1000. Didn't sleep until off Sri Lanka, therefore at about 2am SYD time. Had a few hours, woke up over Abu Dhabi...slept a little more until just near IST, stayed awake the rest of the way. Arrived in LHR at 0530, connected on BA to MUC, arrived at 11am, stayed up until 2030 MUC time. Tiredness of the antipodean flight meant good sleep until about 8am the next morning. Excellent!
Felt very good and acclimatised.
QF 2 LHR-BKK-SYD
times are local
went to performance of Macbeth at Stratford-upon-Avon the night before I left. Got back to accomodation at 11pm, packed musical instruments etc. (was an orchestra tour), slept at 0030. Woke at 0600, quick breakfast (light), rode to LHR in coach, arrived at about 0900. Dep on time at 1215.
I did NOT sleep at all from LHR-BKK, therefore very boring
that's the key.
arr BKK 0700 dep. 0810
QF served a brunch, ate that and then by this stage, the eyes couldn't stay open any longer since short sleep in England (only 5 hrs) and LHR-BKK no sleep, so 5 hours sleep and continuous 20 hours awake meant I went straight to sleep from the Gulf of Thailand until the middle of Australia, about 6 hours of sleep, in uncomfortable QF economy...not bad huh?
no sleep until arrival.
Arr. 1945 at SYD
By this stage, because the tiredness of the journey set in, sleep was easy at about 2200 SYD time which meant that waking up the next morning I was in the correct time zone
Was I just lucky? If not, I hope that's a strategy that people can use (though with most of the LHR-XXX-SYD flights arriving in the morning in SYD now, I don't know whether it'll work).
