Hi @Repair12345,
Welcome to the Bunnings Workshop community, it is wonderful to have you with us.
The best method of repair depends on the size of the hole.
Luckily, we have some easy-to-follow guides that will walk you through the process regardless of the size of the hole.
Check out How to Fix a Hole in the Wall and How To Repair A Large Hole In Plasterboard for some guidance.
If there is anything you are not sure of, please let us know so we can assist further.
