Australian and New Zealand Gardening: Help with Box Hedge, 1 by Beakybaby

my box hedge is turning a shade of red and I noticed the affected plants have nodules on them but this is not on any of my healthy hedges. I have looked online and cannot confirm this is blight. Hope someone can help as I would like to dispose carefully asap if this is blight as I have a lot of box hedges around my property and would not wish this to spread. I have enclosed a photo and this seems to occur on the hedges that have been affected. I am on the Central Coast. Any help would be much appreciated. Thanks
