Anti-Australia Day posters and graffiti have been plastered across Melbourne's CBD as hundreds of people rally outside Parliament House over Aboriginal rights.  
The large posters featuring the Aboriginal flag, which read "Sovereignty Never Ceded" and include the slogans #InvasionDay2016 and #NoPrideInGenocide, have been placed over existing advertisements at tram stops and train stations in the CBD.
Two posters have been placed inside AdShel advertisement display screens outside Southern Cross Station. One of the posters at the station suggests Australians are "celebrating 228 years of genocide". 
Meanwhile, the words "Happy Invasion Day" have been sprayed on the walls of Parliament Station.
The graffiti appeared shortly before hundreds of people gathered on Spring Street to protest against Australia Day celebrations.
Speakers at the rally participated in a smoking ceremony, before placing flowers on the steps of Parliament House where they called for action to "stop the genocide of our people... stop the destruction of our land". 
One protester also took red chalk to the Parliament of Victoria sign, making it resemble the Aboriginal flag, before the group made their way along Bourke Street chanting: "No pride in genocide."
Nearby, thousands of people lined Swanston Street to watch as four Australian flags were raised outside Melbourne's Town Hall, before the annual Australia Day parade.
More than 100 community and cultural groups, including the Country Fire Authority, are participating in the parade from Swanston Street to St Kilda Road.
