At least four Australian cities are set to come together this weekend to push for marriage equality.
Marches are planned in Sydney and Perth on Sunday.
Rallies also took place in Brisbane and Hobart on Saturday.
Those in New South Wales will march up Oxford Street in Sydney on Sunday, and those in Perth will meet at Forrest Chase.
Organisers hope to call on MPs to vote for equality legislation.
Today in Hobart, Tasmania, 1,500 squashed themselves into the city hall to show their support.
The marches come ahead of the resuming of the federal parliament this week, after which a cross-party bill for same-sex marriage will be introduced.
Rallies have already taken place this year, to push for MPs to be given a free vote on the issue.
Same-sex marriage has proven difficult in Australia, and Prime Minister Tony Abbott is a staunch opponent.
Voices from across the political spectrum are loudening in the calls for the legalisation of marriage equality.
