The Baby hitmaker has jetted Down Under to support his longtime pastor Carl Lentz and attend the Hillsong Conference, a five-day religious event in Sydney.

On Monday (29Jun15), his rumoured girlfriend Hailey Baldwin also arrived in the city and headed out on a shopping trip, but Bieber decided on a different kind of rest and relaxation - he wore a droopy, stick-on moustache and large dark glasses as he skateboarded around the city's Bondi Beach area.

The singer also headed to the city's popular health club, Bondi Icebergs, where he enjoyed a workout and a sauna but reportedly clashed with another customer over his poor steam room etiquette.

One onlooker tells the Sydney Daily Telegraph, "In true Bergs form, he was told off by one of the locals for not closing the door fast enough."
