Transcript for Broadway shows resume in Australia, the first country to lift theater restrictions
Reporter: Musical theater fans around the world -- for the first time in forever Reporter: Waiting for this very moment, a return to the stage. Nothing's in my way When I walked out for the first time on the stage -- don't let them in I got emotional. Because I was looking out to - this amazing theater, we're here, this is happening. It was so exciting. It was this moment that I'd dreamt about, literally dreamt about, for months. Reporter: Broadway shows like "Frozen" and "Hamilton" finally opening their doors for audiences in Australia. Since the beginning of the pandemic, Australia has successfully contained the virus, reporting 29,000 cases total. Less than 1,000 deaths. About 150 active cases. Welcome back to the capital theater -- Reporter: All of this making it possible to welcome back theatergoers after nearly nine dark months. The cast comes rushing on stage in their costumes. And there's this beautiful moment that they've decided to open up the castle up that's been locked away. And I realize, oh my god, "Frozen" is about this. What did it do to your heart? We all burst into tears. Reporter: As they say, the show must go on. With audience members sitting shoulder to shoulder and actors performing unmasked on stage, Australians have adapted to protocol developed by their department of health and epdeal on thes. Preopening was no small feat. The production team, performers, musicians, crew, wardrobe, are tested every day. Reporter: New audience procedures incding contact tracing and preordering refreshments. We use a protocol which we call arrival windows. They have a time before the show that we'd like them to arrive. Trying to minimize the time that people are spending face-to-face in the foyers and theater. Reporter: Over 150,000 audience members have passed through the capitol theater's doors at 100% capacity.- the only disruption happened around Christmas when "Frozen" chose to cancel four shows as cases spiked locally. We're getting high compliance with all of the protocols. And I can't thank the theatergoers enough. Reporter: "Frozen" put dozens of actors and dancers back to work in Sydney. The production is part of the Walt Disney company, the parent company of ABC news. After "Frozen's" successful opening, other marquee shows began following suit. "Harry potter and the cursed child" began bewitching children in February. Harry potter! Reporter: Then in March, lin-manuel Miranda's "Hamilton." How have you had to reimagine what theater will look like in this new world we're all entering? When you look at what happened for us in Australia, the audience is waiting to engage. They want to engage safely. They want the performers and the musicians and the crew to be safe. Reporter: Thomas shoemaker flew 22 hours and quarantined two weeks to oversee "Frozen's" grand opening Thoughtful and nimble and safety-minded. We can protect the actors on stage, protect the people in the orchestra pit, protect everyone backstage, and do our best to protect the audience. Reporter: For the actresses who play princess Anna and Elsa, being backstage feels the same. Seeing these beautiful ensemble members running out, feeling that sense of community, it was just beautiful. And very literal to what was going on. But it's only for today it's only for today Reporter: But actually performing on stage presents a different experience and a challenge. What we can see as performers out into the auditorium, we can see everyone wearing masks. So you're not seeing the smiles. You're feeling the smiles, though, I would have to say. You still hear the cheers, you still hear the laughter, so you're not completely disconnected in that sense. No matter your sin you're welcome here Reporter: The next show fans anticipate in Australia is tomeny-nominated mu Lin rouge, set to open in August. The moulin rouge is a state of mind Reporter: That show, like every theatrical production, has been dark in the U.S. For an entire year. A pain felt across Broadway. The still-empty streets of manhat rict. Shoemaker is using Australia's success as a model for Broadway's reopening. It's a blueprint. Not a literal blueprint. We won't do the exact same protocols. We're going to work things out. Australia is not us. Reporter: Promises from U.S. Politicians that the show will go on in New York for the 97,000 New York cast and crew members who lost their jobs last March. The show must go on. And the show will go on on Broadway. Will it be tomorrow? No. Will it be in five months? Hope so. Reporter: Will it be challenging? We need to put tickets on sale in advance. We need to rehearse the company. Take me back to March 2020. What was it like for you when Broadway went dark? We didn't understand how deep this was going to go and how deep the impact was going to be. For every worker, seen and unseen, in the theater. That's been profound. Reporter: The great white way strategizing to rebuild and recoup major losses. Last season we were up, a record-breaking season. It's going to take time to get tourists back. Any estimate how much money has been lost, the cost of this It's ormous. And I don't have that number at my fingertips because it keeps shifting every day. Reporter: But hope is on the horizon. The crowds will come back. The people will come back. The artists will be back on stage. Having paid a very heavy cost, but they will come back on stage. Tickets are now on sale for limited fall shows in New York. Her prince is by her side Reporter: Including a new York Broadway show centered on princess Diana. What does this moment say about history about the human spirit, about theater, that this awful pandemic that took people that we care about, didn't break us? Art is the chronicle of all history. That's how we hold it in our hearts. When you come to that first performance, you want to have some Kleenex with you.
