When Hugh Jackman kicks off a world tour of his latest stage show in Scotland, a little-known blues singer from an isolated Indigenous community in Western Australia will be joining him on stage.

Olive Knight said the opportunity would be "a dream come true" but also a chance to raise awareness of a heart-breaking issue facing her people.

"I'm doing this regardless of my age," Ms Knight said before jetting off to fulfil an extraordinary highlight of her musical career.

The blues singer from the isolated desert community of Wangkatjungka will turn 73 while she is on the road with Jackman's latest production, The Man. The Music. The Show.

The show will kick off in Glasgow and take in 11 other countries across three continents between now and September.

"I was hesitant about it because of my age," Ms Knight said.

"I saw the doctor who examined me and he says, 'Well don't sit in an armchair and watch the sunset until your dying days, get up and go'."

Backed by a live orchestra, Jackman will perform songs from The Greatest Showman and Les Miserables as well as other Broadway classics.

Ms Knight will speak and sing in her traditional language of Walmatjarri as part of the 'nomad section' of the show which also features her son, singer Clifton Bieundurry and Didgeridoo players Paul Boon and Nathan Mundraby.

Jackman has described their performance as a special part of the production.

"Their language, their culture, their heritage, their music and most importantly their hearts … I want the world to experience all of it," he told the ABC in a statement.

"I'm truly humbled and honoured to stand by Olive's side and pay my respects to her and her ancestral home.

"Olive is an authentic and powerful Walmatjarri and Bunuba woman."

'Light bulb moment'

The musicians' collaboration with Jackman dated back to 2011 when Mr Boon said the actor stumbled across a performance and exhibition they were staging in Los Angeles called Nomad Two Worlds with photographer Russell James.

"The tsunami had just hit Fukushima which cancelled shooting for one of the X-Men movies in Japan," Mr Boon said.

"He [Jackman] had a gap in his schedule and his agent said why don't you start doing this one man show you've always wanted to do.

"He just wanted something to reflect Australia and, lucky for us, he walked into an exhibition in LA we were having … and the light bulb moment when he just went, 'That's what I want in my show,' and that's how it all started."

'A fine gentleman'

Since then, Ms Knight has performed twice alongside Jackman starting with his Back on Broadway musical.

She said this latest world tour was a "dream come true".

"He's got a heart for his country, for his people, for Australia and for Indigenous people," she said.

"I do have such huge respect for him —he's such a fine gentleman."

She says it reminded her of the repetitive sounds and rhythms of the traditional Aboriginal music she was brought up with in the desert.

Although she did not own her own guitar until she was 40, she has released three albums since then.

Tour follows challenging year

Ms Knight said she was looking forward to taking her language and culture to the world stage as well as shining a light on one of the most challenging issues facing her people.

Last year, she lost her grandson to suicide — the second close relative to take his own life in recent years.

She has been campaigning for more resources to tackle suicide in her region which has one of the highest rates in the world.

The crisis has driven her to look for community-led programs including using music as a tool for safeguarding mental health.

"That is one of the things I want to speak loud and strong for," she said.

"Because of all the suicides and depression and things that are taking our youth away from us — who are supposed to be our leaders?"
