I am confused if I am eledgable.

I have an Australian passport.
I am flying Brisbane to Hong Kong. Staying one night
Fly to Shanghai. stay two nights at Disneyland.
Fly to Macau. Spend the night.
Fly home.
I can still get the 72hr free transit when I land in Shanghai?
Was told this was ok. But now its getting closure my anxiety is having doubts?
