One Direction caused chaos in Australia this week and now they're making their fans scream all over the world.

The 1D boys were photographed swimming in Sydney Harbor on Tuesday -- shirtless!

Harry Styles, 17, and Liam Payne, 18, showed off their toned beach bods while boating with Zayn Malik, 19, Louis Tomlinson, 20, and Niall Horan, 18.

The guys also enjoyed some fishing and tweeted their excitement to fans about having a relaxing day off.

"Chilling big time today, Liam Payne went fishing and caught the boat," Horan tweeted. "What a great day! really nice to chill with the lads! Big day tomorrow"

But some 1D fans were disappointed that only Styles and Payne decided to go shirtless! "WHY DIDN'T YOU TAKE YOUR SHIRT OFF HUH? you disappointed your fans jk but next time you better take it off," one fan tweeted at Horan.

Horan replied, "yo I'm really not tanned, if I was tanned then maybe but?"

Fans in Australia were further disappointed when the boys couldn't greet them due to security. "Australia we're here, sorry we couldn't come out, airport police said it wasn't safe," Horan explained, "We really wanted to come out and say hi, cya soon."
