Posted on 20 October, 2018 All volunteers need to submit to a full criminal check completed prior to their deployment. This has been done partly because of Australian Government requirements, but more importantly because we take child safety and protection seriously. Open Heart International has an online service to streamline this process, and we cover the cost associated with the check. A full criminal records check is more expansive than a Working with Children check. Tags:
