GROWING unrest over the Palaszczuk government's management of rural Queensland is set to again see farmers march on Parliament House in Brisbane. The August 20 protest will be led by the newly formed group Dozer Drivers Queensland, which is taking a stand against the Palaszczuk government's controversial approach to both fire and vegetation management. Organiser and heavy machinery contractor Bruce Wagner from Boonah said farmers, contractors and other concerned groups were determined to have their voices heard. "We need to make sure people understand the absolute mess that the Palaszczuk government has made of fire and vegetation management and how these are impacting on the lives of people," Mr Wagner said. "The flawed trigger mapping is an example of just how wrong a government can get it." The timber industry is also organising a rally in Maryborough on August 18. Gayndah hardwood sawmiller Sam Slack said the event had been sparked by a still-to-be released review of native forest code of practice. "The code appears set to shift from leaving 150 stems a hectare to leaving 300 stems a hectare," Mr Slack said. "At that increased density it is too many stems for trees to grow properly. Over time there will be less trees available to harvest and that will put us out of business." Mr Slack said the Maryborough event would show how many people were involved in the industry, including workers, contractors and landholders. The Green Shirts Movement will also be raising awareness about issues affecting Queensland's agricultural and fishing industries during the 10 days of the Ekka from August 9.
