Would I be qualified for 144 hour free transit ?

Hello,
I am an Australian citizen flying Sydney-Singapore where i join a cruise ship that ends in Tianjin (ceuise goes Singapore, Vietnam, Hong Kong, South Korea, Tianjin) i am intending to stay one night in Tianjin before flying back home to Sydney.
Does this qualify for the 144hr free transit? Is there a counter at Tianjin port where this visa is issued upon arrival?
Thanks kindly!
