Fiji's interim government claims 2 million US dollars is collected by trade unions from members every year.
In a statement, the regime says calls have been made for reviews to union leadership following a growing dissatisfaction amongst union members over the decision by some union leaders to invite international sanctions against Fiji.
Several unionists have been in New Zealand and Australia requesting support to fight against alleged violence and harassment by Fiji's regime.
They deny the salaries and perks claimed by the government.
But the Permanent Secretary of Information, Sharon Smith- Johns alleges members are worried that union leaders are politicising issues and have joined what she calls Anti-Fiji Movements overseas.
She says the government has the right to be concerned.
