Calm yourself ladies: Harry Styles went swimming off a luxury yacht in brightly coloured shorts as One Direction let their hair down in Sydney

Louis Tomlinson looks like he's sponsored by Corona, as he no doubt sips from a stocked up on-board fridge spilling with every possible treat One Direction once dreamed about while at school.

The boyband lapped up the life of luxury aboard a yacht off Sydney Harbour, diving into the sea, drinking refreshing beer and topping up their already sunkissed bodies from having been in the US.

Zayn Malik, Louis and Harry Styles went for a spin on a power boat, while Liam Payne tried his hand at fishing and Niall Horan remained covered up, perhaps to stop from burning his Irish complexion.

The British X Factor graduates have already conquered the American market following their tour across the country, which caused hysteria among their new fans.

And Zayn wasted no time making an impact on Oz fans as soon as they landed in Australia.

The 19-year-old treated waiting fans by standing at a window topless to show off his heart tattoo.

The group arrived in Sydney fresh from their American and Canadian trek yesterday.

And they wasted no time getting acquainted with their devotees Down Under.

Zayn carried a water bottle to their hotel window as he posed with his top off and wore just a chain around his neck with his trousers on show.

But while he was happy to bare himself for all of the fans below, band favourite Harry didn't give them the same treat.

The curly haired teenager was seen standing next to his bandmate as he peered out with a white T-shirt on and sunglasses hanging off his neckline.

His pensive expression was hard to gauge, but perhaps he was sparing a thought for Lily Halpern.

Caroline Flack's former squeeze is rumoured to be dating the 19-year-old American singer, a Boston teenager who has supported the likes of Big Time Rush, Cody Simpson and Greyson Chance.

While the New York Post claims 'they've been seeing each other for a few months', and Lily was seen leaving Harry's hotel room in the Big Apple last month, the band's spokesperson denied the claim.

It may have been a shock arriving in the country as the boys had to be escorted by security thanks to the amount of fans anxious to see them, although they are no doubt getting used to the attention.

Harry and Zayn, along with Louis, Liam and Niall, were seen being ushered into their waiting vehicle as they stepped off the plane.

Louis was dressed in a beanie hat with jeans, a T-shirt and hoodie, while Zayn initially covered up in a grey T-shirt and black leather jacket.

And even at the airport they had hordes of fans waiting for them with messages written on boards as they walked through to make their way to their new hotel.

Next week, the boys will be seen adding another string to their bow as they guest-star on US show iCarly - which has already aired across the Atlantic.

The episode, which will feature them singing their infectious pop track What Makes You Beautiful, will air on April 16 at 5.30pm on Nickelodeon UK.
