Hi there,
Welcome to the forum.
If you look at this link Temporary Business (Long Stay) - Standard Business Sponsorship (Subclass 457) it states "Any secondary applicants granted this visa are given full work and study rights."
If you haven't already, why not email the Correctional Services Department and ask the question. I'm sure it won't be the first time it's been asked.
