Yes, I have not only looked online but have visited Sea Power in Canberra where the records are held. As you can guess, there are more records in existence than have been digitised. For example, the AFOs & CNOs on line are only part of those documents they hold. A fascinating place to visit, well organised and they are very helpful. Last visit they had scanned an ABR19 they had and dropped in onto a usb for me to simply copy onto my notebook. You have to book in advance to organanise a day or two to be there, you donít just turn up on their doorstep and expect to be admitted. The Historical Branch is just part of Sea Power. Their Director happens also to be a model maker.
The blue historical documents are from the national Archives of Australia and available online.
