Justin Bieber has posted a heartfelt message to fans wanting to meet him during his time in Australia begging them to respect his boundaries.

Bieber arrived at Melbourne Airport on Sunday morning and was immediately surrounded by around 100 screaming fans and paparazzi. He is due in New Zealand on Thursday.

"I want to enjoy the moment just as you're enjoying the moment but I can't enjoy it if I feel like there isn't any respect given to me at that moment," Bieber said via image-sharing app Snapchat.

"If I'm walking somewhere or arriving somewhere and you guys are asking to take a photo, if I don't respond, if I continue just walking, the likelihood is probably that I don't want to take a photo at that moment.

"Now if you start screaming louder that's not going to make me want to take a photo more."

Bieber will perform for fans in Melbourne on Monday morning at a rooftop radio gig to promote his new single What Do You Mean? before flying to Sydney, where he will appear on the X Factor stage on Tuesday.

The pop singer will then jet out to a secret location on Sydney Harbour, dubbed "Bieber Island", for a concert presented by KIIS radio and iHeartRadioAU Australia.

"If you're asking kindly, usually the chances are I'll take a photo, but if perhaps I don't or I'm in a mood where I'm not trying to take a photo at that moment, please just respect me and just treat me the way that you'd want to be treated," he said.

"Because honestly, I'd rather stand there and talk to you for five minutes and not take any photos and us be able to have that moment rather than just chaos."

Bieber also asked fans to reconsider exactly why it was they wanted to meet him.

"Why did you travel to see me in the first place?" he asked. "Was it really to see me? Or was it to get that moment of you seeing me so that you could tell people about it?"

Bieber will play an intimate showcase for invited fans and media in Auckland on Thursday, and will host a barbeque the following day.
