The rally continues a campaign started by hunger-striking farmer, Peter Spencer, and a mammoth protest in Canberra last month.

Organisers and former cattle producers, Bob and Jeanette Jones, Coffs Harbour, are leading the charge with the rally and are expecting thousands of people to attend.

Mrs Jones said farmers were already aboard buses on their way to the city from Bourke, Nyngan and Deniliquin, with others from the Central West and North Coast expected to join them.

She said others from across the State would also make their way to Sydney by private transport.

Mrs Jones said there were many speakers lending their voice to the campaign, including members of the Caroona Action Group and Mr Spencer himself.

She said one of the key outcomes of today's protest would be the establishment of a “property rights and right use of lands” committee.

Mrs Jones will invite 12 people to be part of the committee in the coming week, with a mix of both males and females she hopes will lobby organizations and governments.

“We’ll definitely be forming a committee of 12 people who will represent various areas of farming on behalf of all farmers,” Mrs Jones said.

As well, she hopes the rally will help “galvanise” the support of both country and urban residents to the cause.

“We want to unite the country with the city,” Mrs Jones said.

The rally will get underway at Hyde Park from 9am this morning, with speakers addressing those gathered from 9.30am.

They will then march to Parliament House at 10.50, with more speakers at Parliament from 11am.
