'Magic is real': Harry Potter and The Cursed Child receives standing ovation at first preview J.K. Rowling hits out at racists after Harry Potter play casts black Hermione Harry Potter and The Cursed Child first pictures revealed 
It's the musical that every major theatre producer around the world is clamouring for - the two-part stage show Harry Potter and the Cursed Child. 
Best-selling author J.K. Rowling is a co-producer of the show, which began previews on London's West End this week, along with Sonia Friedman Productions.
Speculation about whether the production will come to Australia is rife even before opening night on   July 30.
Rowling, the creator of the Harry Potter series, which became a hugely successful film franchise, has said no decision would be made until after the world premiere.
Yet if there's any company in the box seat to tour the show overseas, and bring it to Australia in particular, it's the Ambassador Theatre Group.
And it wouldn't even have to wave a magic wand, as it is already connected to the production.
Sonia Friedman Productions is a subsidiary of the Ambassador, which has several venues in Sydney. It has a 15-year lease to renew and operate the Theatre Royal. 
Ambassador founder Sir Howard Panter??? has also flagged plans for a third theatre venue in Sydney's west.
Asked whether Ambassador would bring the Harry Potter stage show to Australia, the company's Asia Pacific spokeswoman did not rule it out, but said no decision would be made until after the show has opened.
The publicist confirmed that Ambassador was working with Sonia Friedman Productions on the West End premiere.
"There are just no plans beyond the West End opening," the spokeswoman said. "We have no plans past that, [we'll] see how that goes really.
"There are three different producers of the show, [that] will come into account."
While its Asia Pacific headquarters and venues are in Sydney, ATG has toured shows around Australia, to mixed reception.
Its productions here have included Legally Blonde the Musical, Thriller Live, The Rocky Horror Show, Guys and Dolls and West Side Story.
Chief exec Tim McFarlane has said previously the group was in active discussions for other Australian venues, in each of the capital cities. 
Harry Potter and the Cursed Child is staged in two parts, which run for more than two-and-a-half hours each. Its West End run will continue until at least   May 2017.
Sonia Friedman Productions is also a producer on the West End run of The Book of Mormon, written by South Park creators Trey Parker and Matt Stone with Robert Lopez. The Book of Mormon opens in Melbourne in early 2017. It is also a co-producer of West End musical Sunny Afternoon, which features songs by the The Kinks, written by expatriate Australian Joe Penhall???.
There's a Melbourne connection to the production too - Harry Potter and the Cursed Child director John Tiffany, has had another show open here: the musical Once, which producer John Frost brought to the Princess Theatre with the Melbourne Theatre Company in 2014 after runs in New York and London.
Frost is one of Australia's biggest theatre producers and has also co-produced shows on the West End and Broadway, including The Bodyguard, Blithe Spirit, An Act of God and Fiddler on the Roof. He's one of few with the clout to bring the show here.
