A 'meet and greet' rally for concerned community members will be held tomorrow (Saturday) from 9am to 1pm at the corner of Duralie Road and the Bucketts Way, Gloucester.

On Monday, a rally will be held in Sydney's Martin Place from 8.30am, outside the headquarters of Channel 7, and before the resumption of the Land and Environment Court hearing at 10am.

Ironstone Community Action Group (ICAG) is part-way through a Merits Appeal Class 1 action against NSW Planning, Gloucester Coal and Duralie Coal, in an effort to protect the Gloucester valley and its river systems from the results of coal and gas mining.

The group claims government approvals to the burgeoning mining industries of the Gloucester region are having an effect on wildlife, creeks and rivers, people's health, and in particular the drinking water of Stroud and Stroud Road townships, as well as the Manning catchment as far as Taree.

Hearing of the action began in May in Gloucester and was adjourned part-heard. More evidence is expected to be taken on Monday, and at another scheduled hearing date, Friday July 1.

Water ecologist Dr Ian Wright, who is part-way through giving evidence, is expected to return to the stand on Monday.

Next Friday has been set down for barristers to present their summaries to the judge and commissioner. Among issues included in the action are resident concerns and complaints on dust, noise and train movements from Duralie and Statford coal mines, and fears over the cumulative impacts from AGL gas drilling and lights disturbing residents etc.

ICAG secretary Amanda Albury has invited concerned people attending the Sydney rally to take along photos that indicate their neighbourhoods are under attack from coal, gas other mining companies and their effects on natural water sources, agricultural land, bushland habitat for wildlife and industries such as farming, oyster production, fishing, tourism and food production.

Tomorrow's 'meet and greet' rally near Gloucester is to give information to local people, and for tourists to be shown how coal and gas mining companies in the valley have damaged the environment, Ms Albury said.
