Taking a course to the Land Down Under for promotional duties, Hayden Panettiere lands down at Sydney’s International Airport on Monday, March 30.

The “Heroes” hottie tours abroad, in the company of her mother Leslie, for the Supernova Pop Culture Expo in the city of Brisbane. She’s scheduled for photograph-autograph sessions with fans there.

Out-of-the-way from her spree to Australia, Hayden lately conversed with Britain’s In Style magazine, explaining her wish to have a big family.

She says, “I always said I want four kids - I love kids. I would love to be a mother and to have a family - for Italians, it’s the most important thing you can have.”
