For casual employees; what does regular and systematic work mean?

As to whether or not it was systematic, it has been held that a definition would include something that could fairly be called a system, method or plan;Yaraka Holdings Pty Ltd v Giljevic (2006) 149 IR 399.”From the submissions it is clear that (the employee) specialised and performed specialised work on a regular basis. Such activity would fall into the description in Yaraka Holdings in that it was a system, method or plan. I am satisfied that (she) was employed on a regular and systematic basis.
