When holding a 494 visa in Australia, you must only work in the occupation nominated in your 494 visa application. You cannot work in a different occupation. Further, you can only work for the business that nominated you or an associated entity. Thus, even working online for another Australian employer could breach the condition. If your employment with your sponsor ends, you can stop working or work outside of the above conditions for a limited time up to 180 days in a single period, within this period, you need to find a suitable employer who can sponsor you in the nominated occupation.
