The tale centres on a frog who drinks all the water in the world, causing a drought.

Sofo said her vision was to incorporate indigenous dance, music and language into the opera, as they were integral parts of the indigenous culture.

She said opera, by its nature, tied in all art forms so it was an obvious medium of choice.

“It’s an opportunity to promote indigenous heritage to the local community.

“This is probably the first of its kind in terms of indigenous opera for children,” Ms Sofo said.The opera is performed in three languages: English, Italian and Gunnai, a Victorian indigenous language.

Ms Sofo said the story had poignant messages.

“Tiddalik is a familiarly humorous cautionary tale, yet with poignant messages about greed and a need for sharing our world’s resources,” she said.

The free show is at Federation Hall, Grant St, Southbank, this Friday at 2pm.
