If elected to power, the LNP policy will also create a charter of property rights to guarantee the rights of private property owners and to ensure compensation for any loss that arises from government action.

An independent commission for future foods and fibre would also be established to spearhead the development of world-leading agricultural produce, while a rural water advisory panel would be formed to investigate the impacts of coal seam gas and underground coal gasification on water resources, and opportunities for economic use of ponded water.

The policy announcement follows the State Government's pledge in February to protect strategic cropping lands in legislation.

Queensland is now the only State in Australia in which both sides of government recognise that strategic cropping land should be protected.

LNP Leader John-Paul Langbroek said the most productive agricultural lands should be scientifically identified, be off-limits to mining, housing developments and forestry, and be reserved exclusively for agricultural production.

The LNP would differentiate 'top- quality' agricultural land from other good-quality agricultural land. Such lands should be classed as Category 1 (Strategic Cropping).

"Just as it is unlawful to consider applications to clear vegetation in areas mapped as remnant vegetation, so too should it be unlawful to consider applications for open-cut mines, housing developments or forestry on lands identified as top-quality agricultural lands," he said.

Under an LNP government, Treasury would be directed to publicly report on the flow of mining royalties, and give a factual and precise picture on the job-creation opportunities that have arisen from that reinvestment in each part of Queensland, along with the economic diversification, he said.

"That's is the first step we have to undertake. We need that factual economic modelling first," Mr Langbroek said.
