Jetstar do a fraction, less then 25% of their heavy maintenance in Newcastle. The rest is done in Singapore.
They do however do their heavier overnight/A checks in their newly acquired once busy, now empty ex Qantas hangar.
Looking at the bigger picture, it was probably cheaper to shut down the Qantas MEL maintenance base then it was to build a new hangar for Jetstar.
