Hospitality, manufacturing, tourism and health union United Voice has launched a campaign arguing the Queensland Government is wasting taxpayer money by challenging the mining tax.
The new 'Not in our Names' campaign is petitioning the State Government to spend $300,000 in other parts of the economy instead of joining Fortescue Metals Group in court.
"Campbell Newman says Queensland is broke, and that tens of thousands of jobs and vital community services have to be cut," the campaign's promotion material says.
"But this week he announced he would spend $300,000 of our money joining a High Court challenge against the Mining tax – so his mates like Clive Palmer don’t have to pay the tax."
Earlier this month QLD state attorney general Jarrod Bleijie said the state's decision to join FMG had been made on crown legal advice.
While Bleijie said FMG's arguments were "valid" Western Australia has declined a similar move and said previously a High Court challenge was unlikely to succeed.
