Welcome to another issue of AOS News. We have a range of articles, with details of some of the International Year of Light events that took place last year and a report on the KOALA conference as well as articles on graphene oxide films and astrophotonics. Other items in this issue include an article about Australia’s involvement in the gravitational wave discovery and our ‘Optics in Everyday Life’ section, which looks at periscopes. I hope you enjoy reading them all.
