The Veronicas have one of the strangest backstage demands in Australian music – and it all started with a mortifying mistake.

“We’ve lost our voices from too much hairspray before, it’s so embarrassing,” Jess Origliasso reveals.

It’s a confession that explains the duo’s now-strict “no spray policy” – no hairspray, no face spray and absolutely no fragrance of any kind. The rule is so rigid that the sisters can’t even jump in a regular Uber if it has one of those dangling air fresheners.

“We have to get a hire car to specifically say we cannot have fragrance in the car,” Lisa explains. Even their backstage crew are banned from wearing perfume, “fragrance and sprays are just an absolute no … The deodorants have to go.”

But vocal preservation isn’t the only thing on the agenda for the iconic Aussie duo. They’re also clearing out their archives, selling off pieces of Veronica’s history on eBay – including Lisa’s iconic hoop earrings (bought with their first record deal paycheck) and Jess’s 2006 Alexander McQueen skull scarf that’s “been through quite the lifetime.”

As for the wildest celeb to slide into their DMs? Jess reveals that years ago, Courtney Love sent her phone number. “I called her and there were two weeks of really fun craziness … I hope that sounds as saucy as it was.”

Here the sisters divulge even more – from their make-up must-haves, to their best unsexy beauty hacks and the three items they always travel with.

Jess: “We’re both very sensitive so it’s been a journey to find skincare that works for us. Right now I use the Tower 28 cleanser because it’s so good for sensitive skin and it works perfectly.”

WHAT’S ONE THING WE’D BE SURPRISED TO FIND IN YOUR BATHROOM?

Jess: “I think people would be surprised to find that we don’t have any perfume.”

Lisa: “Historically, our pheromones were our natural perfume and it was used to attract mates because if your pheromones are compatible, it goes to show how compatible’s the chemistry.”

WHAT ARE THE THREE ESSENTIAL ITEMS IN YOUR CARRY-ON?

Jess: “Eye mask, a pillow and ear plugs. The beeswax earplugs block everything out, it is true bliss. I’ll watch movies with the captions on and not listen.”
