Just when we thought they were all done with their massive promotional tour, Zac Efron, Vanessa Hudgens, and Ashley Tisdale were spotted on their way to Australia.

The “High School Musical 3: Senior Year” hotties looked a bit worn out as they arrived at LAX International Airport in preparation to fly out last night (November 7).

Vanessa, Ashley, and Zac will be spending the next few days premiering the film as well as giving their Aussie fans plenty of opportunities to see them at various promotional appearances.

Of her HSM co-stars, Miss Tisdale recently told FOX Pop Tarts how much she enjoys seeing their love for each other. "I'm a total romantic, I loved watching romantic comedies growing up like 'My Best Friend's Wedding' and so obviously, like, I just love watching Zac and Vanessa because it is such a sweet and romantic relationship so of course you're like, 'aww' whenever they kiss and everything. But just watching them on set is really awesome, it's beautiful."
