Why know your copyright basics?
Your work is protected as soon as you create it, but if someone copies it, you will have to show that it is yours and since when. Australia has no official copyright register, so the evidence is up to you: knowing your rights helps you react in time and keep the right records.
For that evidence, a copyright registration with Copyright-Australia.com keeps your work with a certified date. To warn others, create your copyright notice in one click.
