Yes, I can assure you there is a shortage of techs and what has happened with Visionstream has introduced a spanner in the works with the training of dozens of apprentices Downer and Transfield employed. Downer and Transfield both were staffed very lean and found it hard to recruit suitable staff. Hence the techs brought in from africa and asia
I'm not sure whether the options are good or not, from my understanding of the VS contract it appears to be a smaller version of the contracts telecom/chorus have always had with Downer/transfield. That degree of risk is do-able for a large corporation who can tolerate a level of risk and aborb losses over an entire country. How well that will translate to small owner-operator businesses I'm not sure.
