Industry bosses and the NT Chamber of Commerce say pay rates of around $3,000 a week may not be enough to attract gas workers to the NT.
NT News reports a rate of $1489 a week has been agreed upon between unions and contractors Macmahon and John Holland for work on the $34 billion Ichthys project.
The figure is only for a 38-hour week, and according to NT News many workers are more likely to put in around 56 hours.
With overtime and allowances the work is likely to push employee payments above $150,000 a year.
But NT Chamber of Commerce workplace relations manager Michael Maloney said the gas industry was crying out for workers and pay rates needed to be high to attract labour.
"It's not easy being a construction worker up here. I wouldn't do it," he said.
According to the Hays Oil and Gas Global Salary Guide 2012 Australians are the second highest paid workers in the global oil and gas industry.
The report, released earlier this year, said workers in Australia's oil and gas industry earned an average $164,000 a year.
Foreign talent in Australia earns more, at an average $173,100.
