I know it has been answered here that you can travel as a tourist on a business stream of subclass 600.
But another online source suggested otherwise that the purpose of your trip must be that of the stream you've been granted a visa for.
Also on my grant, it is stating clearly it is on a "Tourist" stream. So I'm a little worried if I should be applying for another one of a "correct" stream or not. Anyone on a similar situation recently or got any official quote from the Aussie immigration?
