The federal education minister, Jason Clare, says the “drip feed” of information about the work history of alleged paedophile Joshua Dale Brown highlights the urgent need for a national database to track childcare workers. On Wednesday, another childcare centre was confirmed by police as being among Brown’s work history, bringing the total number of his known childcare workplaces to 23. That’s just one of the things that we need to do.”Clare said authorities “should be able to press a button” and know Brown’s work history. It would also require all childcare centres to adopt the federal ban on personal devices by 26 September or face fines up to $50,000. Police said establishing Brown’s complete work history had been “extremely complex” as childcare providers do not have centralised records.
