I am flying from Sydney to Shanghai, will have 3-4 days in Shanghai

and then have a flight to HK with a 2 hour layover for a quick business meeting at the airport before heading back to Sydney. My flight will be qantas - Syd-PVG and then return is PVG (Dragon Air to HK) 2 hr layover at airport and then qantas to Sydney. Will I be eligible for the free transit. I hold an AU passport.
