He joined with Australian Greens deputy leader Senator Larissa Waters to call on the Queensland Labor Party and the Coalition to “play it straight with Queenslanders” about the mine.
“Queenslanders are being kept in the dark about the environmental impact of this mega coal mine and the number of jobs it will create,” he said.
“An Adani expert under oath said there would be 1500 jobs or less, but Prime Minister Turnbull and Premier [Anastacia] Palaszczuk say it will create up to 10,000.
“If they have confidence in this figure, why don’t they release the modelling, what are they afraid of?”
Brown also asked whether the proposed mine would damage to the Great Artesian Basin aquifers and the availability of groundwater.
“The Adani mega coal mine is this generation's Franklin River,” he said.
“Just like in 1983, people power will stop it.”
