Justin Bieber is back in town.

The singer could have been mistaken for any number of the shirtless men performing chin-ups on Bondi's waterfront on Tuesday morning, however hawk-eyed fans spotted his trademark tattoos as he strolled along the sunny promenade, smiling and shirtless.

The 23-year-old What Do You Mean star is reportedly back in Australia to attend the annual Hillsong Conference - a religious Coachella - out at Homebush in Sydney's inner west.

The theme of the event, which also takes place in London and the United States later this year, is "Closer".

"This conference gathers the greater church, inspires fresh vision and hope for the future, and equips every individual to walk out the call of God on their life," a mission statement published on the church's official website stated.

"It inspires leaders and believers alike to make a difference in their sphere of influence for Kingdom's cause. It equips the church with God-breathed sessions, practical tools, and connection."

Tickets to the three-day event start at $359.

Bieber began his day in Bondi by wandering up the aisle of Hall Street to the altar of capitalism, the new Louis Vuitton pop-up store, to view the new Supreme capsule. Despite already owning a number of pieces of the skate-inspired collection, Bieber and his small entourage were given a private shopping experience. 

He then popped into popular eatery Bills and was spotted outside Doughnut Time.

Prior to touching down down under, Bieber performed at the British Summer Time Festival in London's Hyde Park at the weekend wearing a baseball shirt from the aforementioned LVxSupreme collection.

Appearing on the bill alongside Phil Collins - who needed to take the stage with a walking stick - and Blondie, Bieber, who was suffering a cold, disappointed fans by miming most of his set list.

"Backstage I have a Vicks inhaler and I'm using Olbas inhalers, they're the greatest of all time are they not? I used a Vicks one and all that medicine stuff is stuck in my nose right now, and I'm having a rough night. Don't judge me," he told the crowd.
