If it's anything like the EK 404 SIN-MEL, they'll dinner service after take off takes about 2 hours, and there's a full breakfast service before arrival in Melbourne that starts 1.5 to 2 hours before arrival. Between that, and a cabin packed 7 across, sleep time is rather minimal for these sectors, IMO.

OP, here's one review of the EK lounge at MEL; http://milesdownunder.com/2015/01/re...nge-melbourne/ I assume much like their counterpart in Singapore, the lounge keeps the food going till the last departure and as such having your fill on the ground to try and get sleep once on board is quite possible (cabin lights/noise permitting).
