Grad Trip???

Out of boredom, I surfed websites of budget airlines.

To Taipei
Jetstar -- $158 X 2 = $316 per pax

To Macau
Jetstar -- $78 (departure) + $89 ( return) = $167 per pax
Tigerair -- $39.99 X 2 = $79.98 per pax
(if going Hong Kong can take ferry from Macau)

To Australia (Melbourne - Tullamarine)
Jetstar -- $298 (departure) + $468 (return) = $766 per pax
Tigerair -- $239.99 (departure) + $699.99 (return) = $939.98 per pax

If we are really keen in going for grad trip then we will need to book tickets soon. Should we make a trip to Chinatown one of these days?
