Niall Horan, Liam Payne and Louis Tomlinson have jetted Down Under following an insanely busy month that has already seen them visit Los Angeles, New York and London.
Bandmates Harry Styles and Zayn Malik (and Zayn's amazing hair) weren't pictured at the airport, with reports saying they caught a different flight.
We don't know how 1D do it. We would be EXHAUSTED with their hectic schedule!
They arrived in Oz following an evening at the American Music Awards in Los Angeles, where they performed new song 'Night Changes' and took home three awards including 'Artist of the Year'.
Prior to that, they were in New York for a big appearance on the Today breakfast show, and in London recording their vocals for the Band Aid 30 song.
Today, they added Australia to their long list of countries visit in 2014, touching down ahead of an appearance at the Australian Recording Industry Association Awards (ARIAs).
They'll bring their tour to Oz next year.
Fans lined the airport for the chance to glimpse 1D – and Five Seconds of Summer, who also arrived back home in Australia for the ARIAs.
Unfortunately for fans, though, it seems the bands were a bit jetlagged following their long haul flight and were quickly whisked into waiting cars.
