In the wake of the recent alleged suspension of up to 400 security licenses in Victoria, we speak with Peter Johnson of the compliance department within ASIAL, Tim Sell of the International Security Training Academy and David Dettmann, former Superintendent in charge of security licensing with Victorian Police about the challenges around security licensing in Victoria. Are character references an appropriate  form of probity check? Why does Victoria allow holders of holiday and overseas student visas to work in security and how many of these issues could be addressed through the introduction of a national license?
