It might not be easy for a teenage music superstar to stay grounded but Bieber thinks it's possible if you're surrounded by the right people.
Interviewed on the Seven Network's Today Tonight programme, he was asked what had been the best piece of advice he had received.
"I'd probably say, you know, just to stay humble and keep your family close, keep the people that were there at the beginning there, because those are the people who cared and care enough to stay with you," Bieber said.
"The relationship with my family, always I keep that first. Last time I was here (in Australia) my grandparents were here with me.
"You need to pull up your pants, that's what my grandparents say all the time.
"Like my mum, its always something. They are always super proud of me no matter what... That's what keeps me humble and I do this for them."
The promotional interview with Bieber did not include any tough questions, nor did it probe his personal life or his relationship with Selena Gomez.
The 18-year-old Canadian recorded two songs on Monday for an episode of Australia's Got Talent in Melbourne, where he was mobbed by fans, mostly teenage girls.
He will sing three songs on Seven's Sunrise in Sydney on Wednesday morning.
Bieber said his arrival in Australia this time had not been as frenzied as when he last visited because he was prepared.
"(This time) the car scoots me right when I get off the plane, so I go into the car and can drive right off the tarmac," he said.
