I’m not sure what the ‘industrial court’ is you’re referring to Xeptu. The LHEA is a national award and overseen by Fairwork Australia. They’re the ones that rule on all matters relating to it. What is this ‘industrial court’ you speak of? NSW has the NSW IR commission but it overseas the state awards of things like NSW coppers, nurses, ambos, public service, etc.
Yeah things have changed a bit since I retired and I still use the old terms a bit, The Industrial Court is now the Federal Court that hears Industrial matters.
