Bunurong/Boonwurrung actor and author, Tasma Walton was enjoying her big break on TV show Blue Heelers in the 1990s in Melbourne when a transformative visit from her grandmother launched her in a new direction.

Boonwurrung/Bunurong woman, Tasma grew up in windy Geraldton, in Western Australia in the 1970s, hearing stories from her grandmother about baby whales and women who lived in kelp forests.

These stories always featured a bay and very cold water — neither of which were in Geraldton.

Many years later, while Tasma was filming Blue Heelers and living in St Kilda in Melbourne, her grandmother came to stay, and the stories she had told Tasma over and over again started to make sense.

Except for one tale that had been sanitised for children’s ears — a supposed love story between Tasma's great-great-great grandmother, Nannertgarrook, and a vicious sealer man.

As an adult, Tasma started to research the truth of what had happened to Nannertgarrook, generations ago.
