Little J, he's five and Big Cuz, she's nine. They're a couple of Indigenous Australian kids living with their Nanna and Old Dog. Little J and Big Cuz are busy with the ups and downs of playground and classroom. There's always something surprising going on whether it's at school, in the backyard... or beyond. The gaps in Nanna's ramshackle fence lead to Saltwater, Desert and Freshwater Country. With the help of Nanna and their teacher Ms Chen, Little J and Big Cuz are finding out all about culture, community and country.
