5 Seconds Of Summer have made their triumphant return, today releasing their first track in nearly two years and announcing two exclusive Australian headline gigs. 

After 18 months on the road in support of their 2015 LP, Sounds Good Feels Good, the Sydney-formed outfit have spent the last year living, writing and recording their new album in LA due out later this year. 

Want You Back is the first taste 5SOS fans are getting for the forthcoming record.

"Finally…  It's been three years since our last album and we are so ready to share new music with the world," the band said.

"After spending the last five years on the road since the age of 16, it was important we took time to reflect as individuals and now we’re coming back stronger and more unified than ever. 

"These songs mean the world to us and we have held nothing back in writing and recording this album. We’ve been rehearsing a lot of the new songs live and can’t wait to get back out on tour to connect with our incredible fans."

Check out Want You Back below. 

5SOS will make their return to Australia in May, with shows locked in for Sydney and Melbourne.

Tickets go on sale from 1pm on Friday 2 March; head over to theGuide for more details.
