Chairman of the Cobbora Transition Committee and Dubbo MP Troy Grant yesterday advised that NSW Treasurer Mike Baird and the state-owned Cobbora Holding Company were "offering significant support to our region".

But "no expenditure has been approved, no processes put in place and no projects identified to date", he said.

"These details will be established and announced in the coming weeks," the chairman said.

Mr Grant said across the next three weeks the committee's terms of reference, due diligence and probity arrangements would be established.

"Following that process, I will call a meeting to brief each affected council, and the committee will travel to each affected community to brief and outline the way community engagement in future processes can be achieved," he said.

The chairman asked residents of the local government areas of Dubbo, Warrumbungles, Mid-Western Regional and Wellington to wait a little longer for information.

"I am aware there is some speculation circulating across the community regarding potential funding for specific projects in our area," Mr Grant said.

"I urge everyone to ignore that speculation."

The committee, including Orange MP Andrew Gee and Barwon MP Kevin Humphries, was briefed by the Treasurer and Cobbora Holding Company acting chief executive officer Steve Ireland on Wednesday.

The committee was established in recognition of the "impacts on the affected communities" of the delay in the mine's development.

Top of the committee's agenda is the creation of a transition plan that addresses land management and opportunities for investment and economic growth.

"The committee was fully briefed on the extensive background, current status of Cobbora operations and discussed a potential framework to stimulate opportunities for the communities," Mr Grant said in a statement released yesterday.

Grassroot expectations of injections of $1 million into communities grew after Mr Gee reported to an Orange radio station on Wednesday, and Mr Humphries to a Dubbo radio station yesterday.

It is about six weeks since the state government advised that it would not develop the Cobbora Coal Project, but seek to sell or lease it.

"The decision of the previous state Labor government to develop an uncommercial coal mine at Cobbora created enormous difficulties for the entire state and our local communities," Mr Grant said.

"In response, the O'Farrell/Stoner government has terminated the state's obligation to develop and operate the mine, which would have cost the taxpayers of NSW over $1.5 billion.

"Nevertheless, Cobbora is a large coal resource and the government remains committed to the sale or lease of this asset, noting that an independent planning process for the mine is underway.

"In the interim, our job through the transition committee is to present a clear and productive path forward for local communities."

Mr Grant said the government would make further announcements on the transition plan in coming weeks.

Dubbo's hopes of jobs and business growth were sidelined by the government's announcement in July.

Earlier this week the Warrumbungle Shire Council laid bare the plight of Dunedoo since the Cobbora Holding Company bought 32,500 hectares of agricultural land that had "generated $24 million of annual revenue, supporting 400 direct and indirect jobs in the region".

The council reported of 90 residents leaving the district, impacting on schools, businesses, sporting clubs and volunteer firefighter numbers.
