The CFMEU has agreed to end strikes at the Port Kembla Coal Terminal.
It comes after a number of rolling strikes at the BHP owned coal terminal.
Initial strikes on site began earlier this month after failed enterprise agreement negotiations at the site, where workers demanded a 4.5% pay raise and BHP, the operator of the Port Kembla Coal Terminal, only offered 4.3%.
Unions have now agreed with management over a new workplace deal.
According to the CFMEU, the "breakthrough came after the Port Kembla Coal Terminal board of directors approved of progress made during negotiations last week".
The two have agreed to a 3.5 year Enterprise Bargaining Agreement.
Port Kembla’s general manager Peter Green also welcomed the agreement and the end of the strikes, according to the Illawarra Mercury.
"For many years we have worked hard to place PKCT in a strong position of reliability with our customers by avoiding ship queues; however, the industrial action has threatened our reputation with our service providers, and our customers in domestic and international markets," he said.
