Over 3000 protesters descended on Hyde Park on Sunday for the third instalment of the "March Australia" rallies.

Following the success of marches in March and May, which drew over 10,000 people to each event in Sydney, the rally brought its usual share of colour, noise and creative placards but numbers appeared to be down.

Signs with the phrase "Team Humanity" - a play on Prime Minister Tony Abbott's call for migrants to sign up for "Team Australia", were prominent.



The march began and ended in Hyde Park, looping around Market, George and Park streets. It followed a round of speeches by climate change and indigenous rights campaigners, as well as union officials.

Protest organisers said there were even more reasons to attend marches against the Abbott government since the last march in May.

Fabi M. from the Colectivo Mujer feminist group said attending the marches was critically important.

"We'll see if we achieve something, but I want to be part of it - because if we don't come here, nothing will ever be done," she said.
