Inspired: Kristal West and Zaachariah Fielding, who are musical duo ZK.
As Kristal West steps up to the mic on Sunday night for The Voice, she is carrying with her the determination of her grandfather, indigenous land rights pioneer Eddie Mabo.
The 24-year-old singer from Adelaide says her drive is an unmistakable family trait.
"My grandfather was very driven to fight for his dreams and his dream was to have his land acknowledged as a traditional owner," she said. "My dream is to be recognised with my music."
Drawing on her lineage: Kristal West's grandmother Bonita Mabo will be watching,
Her grandmother Bonita Mabo will be watching, as she did in tears during West's appearance in the blind auditions more than two weeks ago.
"I hope that my grandmother sees the determination that was in my grandfather also in me," West said.
"I've always had such an inspirational role model. He passed away when I was quite young but I had someone who followed his dreams and passions and succeeded."
Contestants on The Voice: Lionel Cole and Sabrina Batshon.
Mabo's 10-year fight in campaigning for indigenous land rights eventually overturned the legal doctrine of terra nullius. West was only a toddler when he died at 55, in 1992, just months before the historic court decision, but her aunt, Gail Mabo, says he was an adoring grandfather.
"Her grandpa was just like everyone's grandpa – you see them, you kiss them and you climb all over them," Gail said.
"Dad was very close to all his grandchildren and he loved them all."
Gail said the family was "buzzing" and glued to West's progress.
"It is a new generation," she said. "They're doing things their own way and making their own mark and doing it proudly."
West appears as one half of duo ZK alongside Zaachariah Fielding.
Taking time out from her job as health worker in Port Augusta, she said of Sunday's battle round: "I hope people see the passion that we have and the connection that we have with our songs. We’re very emotional people and we hope that emotion is delivered through to the audience as well."
