What can we learn from Australia's digital marketing skills shortage?

I’m an English-born Australian who loves both his new country and his industry, digital marketing, an industry I’ve been wedded to since leaving university twenty years ago. When I first arrived in Australia, I quickly learned that digital marketing was propped up by imports, mostly ‘POMs’ like myself with little focus on nurturing local talent.At the time it wasn’t an issue for the industry and there were several key reasons why. Media investment in digital channels was minimal, employees didn’t need to be as highly skilled as they do now to drive results, 457 visas flowed freely, citizenship was almost a guarantee - and us ex-pats even had LAFHA. God, I miss LAFHA.
