airfare booked

I've booked my airfare back to Aust, from 4th Dec to 8th Dec, which is after my last paper (exam) and a day after the submission dateline of CVPR conference paper. Heading to Perth first...a place i always wanna go. Perth has the highest migrated Singaporeans...i always wonder why...few yrs back it was like 30,000 migrated singaporeans in Perth...n i reckon it increased throughout the yrs. I promised my ntu research sup tat i will be back asap...max of 4 days. Well...will keep my promise. :) Everyone...be gd. :P
