THE first international act for Splendour in the Grass 2018 has been confirmed.

English musician Matthew 'Murph' Edward Murphy, the lead vocalist and guitarist of The Wombats, confirmed the news on the band's social media accounts.

"We will be coming to Australia in summer, your winter," he said first during a 41 minute video discussing their latest release and answering fans' questions.

But then it all came out, when at 17 minutes of starting the video, Murphy added: "for anyone listening from Australia we are playing Splendour in the Grass this summer."

"Our manager said we can tell you."

Liverpool band The Wombats released their fourth album, Beautiful People Will Ruin Your Life, on Friday (Saturday morning in Australia).

This album comes after their previous releases: A Guide to Love, Loss & Desperation (2007), This Modern Glitch (2011) and Glitterbug (2015).

Although hardly a surprise, given that the band almost confirmed it last time they were in Australia, it's a novelty for bands to ruin the surprise and confirm they are playing Splendour, as the rights to unveil the line up traditionally belong to triple j.

Splendour in the Grass will be held at North Byron Parklands this July 20-22.
