Australia's 5 Seconds Of Summer are nearing the end of their support slot on One Direction's current tour and confessed that it has been an absolute dream. 

The lads shared a tweet from their collective Twitter account earlier today (July 11) and explained that the European leg of One Direction's Where We Are tour has been such an unforgettable experience:

"Last show of the European tour today, it's been so amazing, you've all been so epic... Can't thank the boys enough for havin' us!"

Tickets for 5SOS's forthcoming 2015 European headlining tour went on sale this morning and they have already sold out several of the dates, which drummer Ashton Irwin addressed in a message to his fan this afternoon:

"In absolute shock that some of the arena shows sold out, what a dream come true to play at these places, can't wait to rock out for you all!"

Calum Hood also shared an update about ticket sales so far and told his followers that their new show will blow their minds, adding: "Thank you to anyone who's bought a ticket for next years tour! We're working hard to make it the best show you've seen!"
