UN calls for consistent climate policy from Australia
The march will proceed down Macquarie Street to the Opera House after speeches and performances calling on those at the Paris climate summit to shift more rapidly to renewable energy.
Sydney march organiser Reece Proudfoot said those taking part in the Australian marches will walk in solidarity with millions of people across the world as part of the global campaign.
Mr Proudfoot said "climate change trains" will shuttle people from Newcastle and the Illawarra to attend the Sydney event
"People from all walks of life are calling for real action on climate change because current targets set by the government are way too low and are leaving Australia at the back of the pack," Mr Proudfoot said.

"It's now clear that a strong people-powered movement is calling for change and won't stand for anything less than solid action on climate change."
Mr Proudfoot welcomed Labor's pledge on Friday to cut carbon emissions by 45 per cent on 2005 levels by 2030, which is well above the coalition pledge of between 26 and 28 per cent.
More than 40,000 people marched in Melbourne's central business district on Friday to kick off the weekend of climate marches, with dozens of events also taking place in regional towns across the country.

Thousands of Canberrans have joined a worldwide protest by marching to support action on climate change.
They gathered on the front lawn of parliament house, a broad cross-section of people from Labor and the Greens to the fireman's union, bee keepers, the Grim Reaper and Tibetan cows - pantomime-style cows that is.
"We are unstoppable, another world is possible," was the chant as the march - estimated by organisers to be as many as 6000 people - set off.
Federal Labor ACT MP Gai Brotmann said people were sending a strong message to the Turnbull government.
"Action is required on climate, credible action and direction action is not that," Ms Brotmann told AAP.
