A police officer has been injured and a man arrested after clashes between police and protesters at an Invasion Day march through inner city Sydney.
Marking the growing debate around the date of Australia Day, thousands of people marched through the heart of Sydney’s Aboriginal community, Redfern, into the city and up to Victoria Park where the Yabun festival is being held.
Police said just before 1:00pm a protester allegedly set fire to a flag within the crowd.
Officers responded by using an extinguisher to put out the fire, and a brief struggle ensued which injured a policeman.
Thick white smoke could be seen coming out of the crowd.
A woman who was participating in the march also sustained minor injuries.
She was treated by paramedics at the scene before being taken to hospital as a precaution.
The police officer has also been taken to hospital for assessment.
A 20-year-old man was arrested and is currently at the Redfern Police Station where he is being questioned.
Police said it was an “isolated incident in an otherwise peaceful demonstration” and overall they were pleased with the behaviour of the crowd.
The march resumed with protesters chanting in opposition to police power and continued on to Victoria Park safely.
There have been no other reports of injuries.
The state's new Premier Gladys Berejiklian condemned the violence.
"We have a democracy and everyone has a right to protest, but today is celebrating everything that brings us together, and I think most people would feel extremely disappointed at what they have seen today," she said.
"It's not acceptable to do that on a day like today, however please feel free to express your views."
Protests held throughout Australia
Hobart had their largest crowd to date at the protest, with Tasmanian Aboriginal Centre president, David Warrener, telling the crowd the date was not appropriate and it continued to be a day of invasion.
Tasmanian Governor Kate Warner added to the debate, arguing changing the date was something for Australians to consider.
In Brisbane, more than a thousand people rallied outside state parliament.
They chanted "change the date" and "always was, always will be Aboriginal land" as they marched through through the city to Musgrave Park.
There will be live music and food at the park, which is a gathering spot for the local Indigenous community.
About 50 people attended a march in Alice Springs, which was tied in with protests against the treatment of children at the Don Dale Detention Centre.
Those at the peaceful demonstration chanted "there's no pride in genocide" and called for January 26 to be a day of national mourning, not celebration.
Among the protestors was Kirra Voller, the sister of Dylan Voller, who was filmed restrained and hooded while in detention at Don Dale.
"I think it's time to change the date … we're still celebrating something on a day that was basically trying to wipe out all of everything," she said.
