Thousands of protesters have hit the streets in Sydney after Donald Trump's inauguration as US president.

A big crowd has turned out in Sydney to rally in support of women, minority groups and immigrants in the wake of Donald Trump's inauguration as 45th President of the United States.

Some social media users estimate the number of participants in Saturday's Women's March through Sydney's CBD at about 5000 people.

The rally started at 11am AEDT, with those taking part marching from from Hyde Park to the US Consulate in Martin Place.

"This is a peaceful protest march to raise our voices in solidarity with those marching around the world," organisers said on the march's website.

"The march is in support of equal rights, fair and civil treatment of women, minorities, and immigrants and against the hatred and bigotry that have been so tragically present in world politics this year.

"We want to provide an opportunity for everyone who is distressed and outraged by the recent political events in the US, and around the world, to voice their dissent against sexism, racism and bigotry."

The local march coincides with an action in the US where hundreds of thousands of people are expected to attend what has been named the Women's March on Washington. The march is a demonstration in support of women's rights taking place on the same day that Trump is sworn in as president.

While the marchers made their way to Martin Place, the word "Trump" appeared overhead, scrawled in the air by a sky-writer.

It's unclear whether the message was in support of, or in protest at, the inauguration of the newest US President.
