A final thank you to Tara Murphy and John Durbridge, our hosts in Sydney, for a fascinating week, meeting with university security and emergency planners, as well as NSW Police. The security challenges we all face are similar and it has been rewarding to learn of the new technology and methods that are being used. Thank you all in Sydney for your time in showing us around and arranging the fantastic visits, including the Opera House this morning (see picture). We hope to see you in the UK soon.
