Residents are being urged to have their say on plans to build a 15,000-home eco-town near Bicester in a consultation which starts tomorrow.
Parkridge, the developer behind the plans for Weston Otmoor, aims to explain its case for the new community to villagers living around the site.
The consultation will include visits by a community relations manager, a project website, a touring roadshow and newsletters, which will be sent to 32,000 households.
But protesters say they do not think the consultation will make any difference.
Weston-on-the-Green resident and Oxford lawyer Tony Henman, who is co-chairman of campaign group Weston Front, said he wanted to encourage as many people as possible to express their opinions.
But he added: "It's something I'm deeply suspicious of. I'm sure they have got the message already they are not wanted. I think it's a box-ticking exercise they're going through.
"Goodness knows what sort of reaction the community relations manager is going to get. I would have thought it would be a thankless task.
"It's not an eco-town - it's either a housing estate, or a new town."
Councillors have claimed Bicester would suffer - or even struggle to survive - if the eco-town was built. Opponents have also pointed out the inability of the A34 to cope with thousands of extra vehicles without any improvements.
The Conservative Party's shadow housing minister, Grant Shapps, visited the site today with local MP Tony Baldry to oppose the plan. He said: "Weston is a prime example of an eco-spin.
"Instead of working with the local people and local democracy, the Government is forcing through development where it's not suitable, in a desperate attempt to meet its arbitrary targets."
Parkridge director Roger Sporle said: "We want to develop a truly sustainable community, with outstanding transport links, which will bring benefits to the wider area.
"We will use local knowledge and experience wherever possible to make Weston Otmoor a place that everyone can be proud of - consultation with local people will play a big part in this."
Parkridge has appointed Weston-on-the-Green firm Mistral Group to manage the consultation, which overlaps with one organised by the Government, which is due to end on Monday.
Mistral director Victoria Cross said: "We're committed to ensuring that all comments, both positive and negative, are considered."
