VIDEO-March in May rallies: Thousands gather to protest against federal budget - ABC News (Australian Broadcasting Corporation)

Thousands of people have gathered in cities across Australia to protest against the Federal Government's 2014 budget.

Protesters angered by the announced budget cuts to Government services - including health and education - gathered in Adelaide, Brisbane, Melbourne, Sydney and Perth today, as part of the nationwide March in May rallies.

In Sydney, the crowd was estimated at up to 10,000 people.

Protesters gathered in Sydney's CBD carrying placards with messages such as "hands off health, education and welfare".

Heather Williams, who works in education, said she was concerned about the Government's changes to unemployment benefits announced in the budget.

"I'm very concerned about the young, unemployed [people] under this budget," she said.

"It really worries me. I know a lot of people who tried very hard to get work."

In Melbourne, the proposed cuts to assistance for unemployed young people were also in focus, as was the lifting of the pension age to 70.

Deputy Greens leader Adam Bandt told the crowd the budget unfairly targets vulnerable people.

"If you say to the Australian people, 'What do you think is better – asking Gina Rinehart and the big banks and the big polluters to pay a bit more or taking the axe to the young and the sick and the poor?' I know which way this country will vote," he said.

In Brisbane, hundreds of people gathered for a rally at Queens Park in the CBD.

Many of the protesters were angry about the announced cuts to a number of government services.

Here are some of the photos from the rallies that were shared on social media.
