你好，你的签证类别是Subclass 855 – Meat Industry Labour Agreement Visa。
在移民局网站上有具体的解释，签证获得后的义务：
Obligations after the visa is granted：
Once a visa has been granted it is not a visa requirement for the employee to remain with the employer that nominated them. However, the employee may have obligations under their employment contracts or industrial laws which may require an appropriate period of notice to be given to the employer prior to ceasing employment.
