You need to apply to CASA for a "Change in Address for Logbook" sticker, which is a sheet of stickers with folding flaps to enable them to track your past addresses. They cost $25 per sticker, and can take 4 to 6 weeks for delivery.
No! Don't even joke about it! Some bureauprat will read it and before you can say "Cost Recovery" we'll all be obliged to subscribe to an address sticker amendment service.
