....in fact you cannot be enrolled in this course until you are an indentured apprentice (at least in my state).
And therein lies part of the problem. Vocational training is still the prerogative of the States. In this State there are a number of ex Cert III and Cert IV college course guys trying to find work, particularly those from overseas whose future in Australia totally depends in them finding full time work in their chosen vocation. Unfortunately most end up driving taxis or working in 7-11 stores.
There is still no substitute for a four year apprenticeship.
