Mr Johns shot to fame as the frontman of Silverchair, whose first album Frogstomp was released in 1995 when the band members were just 15.
Silverchair went on to become one of Australia’s most successful music exports, selling more than 10 million albums worldwide before taking an indefinite hiatus in 2011.
Since then, Mr Johns has worked on multiple different music projects, teaming up with The Veronicas and Empire of the Sun, while also releasing a solo album. Most recently he has been both the host and subject of the hit Spotify podcast Who is Daniel Johns?
Released last year, the podcast offered insight into the extent of Mr Johns’ battles with anxiety disorders, depression and anorexia.
“I used to wait until everyone went to bed and then I would take [my dog] for walks at 2am for like, three hours because I was anorexic, so I was trying to lose weight,” Johns told interviewer Kaitlyn Sawrey.
Mr Johns has been busy preparing to release his second solo album, FutureNever. News of his admission to rehab came just weeks after it was confirmed the album would be delayed until April 22.
According to NSW Police, he has been issued with a field court attendance notice and is due to appear at Raymond Terrace Local Court on April 11.
The two occupants of the second vehicle involved in the crash – a 51-year-old male driver and a 55-year-old female passenger – were treated at the scene, NSW Police said. The woman was taken to John Hunter Hospital for further treatment and has since been released.
