The 13-year-olds won a chance to try out for the junior spin-off of TV show The Voice Australia from thousands of registrations.
The Carramar Primary School pupils will be among groups of 20 budding singers to perform I Still Call Australia Home from memory.
They have also prepared three cover songs should they reach the next stage. Macayler’s choice includes Since You’ve Been Gone by Kelly Clarkson and Izzy has gone for Royals by Lorde.
Izzy’s mother Felicity said the girls, who are both off to specialist programs at Wanneroo Secondary College next year, had done well to make the auditions.
‘Here’s wishing them good luck tomorrow,’ she said.
The singing contest, which aims to uncover the next generation of superstars, is open to eight to 14-year-olds.
Channel Nine will broadcast the show next year.
