spoken by a bloke who clearly doesn't have a clue what the dispatchers actually do.
I'm well aware of what a dispatcher does, this requires a hands on presence to sort out problems and deal with the crew and passengers, which would be difficult from Manila. The "back office" part of dispatch could possibly be done else where.
If you think about it, air traffic control is "outsourced" in many countries. How many ATC centers are located at an airport ? Many controllers never see an actual aircraft as they are located in a building miles away.
Brisbane Centre is responsible for the airspace from 45 nm north of Sydney, up to the airspace boundaries with Indonesia and Papua New Guinea in the north, and east to the airspace boundaries with New Zealand and Fiji.
Better hope Airservices don't get the idea of outsourcing to solve the controller shortage or approach could be handing you over to someone in Asia for the enroute part of your flight.
