For Authority v7.1 users this is the process that Wollondilly will be using. There are a number of ways to extract required data but this is the way that we found worked best for us. Hopefully it may be of some assistance. If anyone needs any further information please reach out. I can be contacted at simone.fisher@wollondilly.nsw.gov.au or 4677 9622.
Thanks
