Moth visitor

As I was putting lights off last night before going to bed, I noticed this large moth on the outside of one of the doors leading to my verandah. He was obviously attracted to one of the lights close to the door. Trying to take a photo of him from the outside just wasn't working so I decided instead to take a photo from the inside, showing his underparts. I tried several shutter speeds: this was 10 seconds. Afterwards I checked his measurement and his wing span was a little over 10 cm. He's gone now. (Any smears are on the door glass, not my camera - I wasn't going to risk losing him by trying to clean the glass first!!!)
