The US Vice President Mike Pence has arrived in Sydney for the Australian leg of his whirlwind Asia-Pacific tour.
NSW Police warns motorists will not be able to park along certain roads, with special clearways set up in and around the Sydney CBD, Kirribilli and Mosman between 10am on Friday and 10am on Monday.
People will see "a range of police resources" around the CBD and Sydney Harbour, and those planning to use public transport, including ferries, are being advised to check ahead for any disruptions.

Mr Pence is expected to take a harbour cruise during his weekend visit. He will depart for Hawaii on Monday.
"There will be a range of traffic changes and a number of special event clearways that will be put in place to facilitate the movements of the vice president, and to ensure minimum disruption to road users," NSW Police Assistant Commissioner Mark Murdoch said in a statement.
"It is our aim to strike a balance between the security needs commensurate with visits of this kind and the needs of the community."
The vice president is accompanied on his 10-day tour of key Asia-Pacific allies by his wife Karen and two daughters, Charlotte and Audrey.
The delegation has already stopped in South Korea, Japan and Indonesia in a trip aimed at reinforcing traditional US alliances.
Mr Pence is expected to turn on the charm for Malcolm Turnbull after that notorious phone call in January, when US President Donald Trump blasted the Australian prime minister over an asylum-seeker deal.
Mr Turnbull says he's looking forward to meeting Mr Pence.

"It is very noteworthy that this is a very early visit, I believe the earliest visit by a vice president to Australia, in the new administration," he told the ABC's 7.30 program on Thursday.
"Many people - including wise people in the media - were sceptical of the Trump administration's commitment to the region, and as you can see the commitment is very real."
