Construction booms have seen apprenticeships skyrocket.

The Building and Construction Industry Training Organisation has seen a 77 percent increase in apprentices in the past two years.

Director Jason Hungerford told Andrew Dickens the average age of apprentices has risen – as people change careers.

"But we're also seeing those that have been part of the construction sector for some time now, choosing to get involved in formal training and that's a really great outcome too in terms of upskilling our workforce."
