The above link contains Opal Tap On/Offs by date, hour and region. In total, there are 8 different regions: Sydney CBD, North Sydney, Chatswood, Macquarie Park, Strathfield, Paramatta, Newcastle & surrounds and Other. Is there a GIS layer of what these regions are? Can this GIS layer be made available alongside this data set so that it is all self contained? Thanks in advance.
