Hypothetical: we are a family of 4 with 2 young boys, If a disaster was to happen and us parents were killed, how would the authoriites know who to get in touch with in the UK? We have emergency contacts here in Australia, but again how would the authorities know who to contact? As far as i know there isn't a national database of emergency contacts or next of kin?
What do you do if your not close enough to people in Australia to have an emergency contact?
