I believe timber flooring is completely unregulated, not only that you can work in teams with no papers of any sort and make money legally - someone else takes the legal responsibility for the floor
I should know, there are quite a few floors in Perth that I worked on under supervision of others. Most of my time was spent doing the considerable hack labour work that is involved in putting down floors
the floor in my house was also done by a team of two people one of them an out of work actor with no qualifications whatsoever
