A list of those granted leave to appear has been released and includes organisations such as the Australian Workers Union, while blocking farmers and the forestry industry.

VFF president Simon Ramsay was "shocked and disappointed" with the decision, given the key role that farmers play in land management and fire prevention.

"The Victorian farming community has been one of the worst affected groups in the wake of the Black Saturday bushfires," Mr Ramsay said.

"This is an appalling decision by the Commission who are essentially placing a higher value on the evidence of the unions than the evidence of farmers and the forestry industry.

"The fires did not start in a union office, they started in rural Victoria and it is appalling that farmers who survived this tragedy will not have the opportunity to present their experience."

According to the VFF, 1500 of its members live in areas affected by the fires.

"For years, the VFF has been at the forefront of lobbying on related issues including the Fire Services Levy and Native Vegetation Regulation. It is only sensible that these issues again be raised in the context of the state’s highest-level of judicial inquiry," Mr Ramsay said.

The Victorian Association of Forestry Industries has also been denied an opportunity to present to the Royal Commission.
