How to patch 3 types of holes in a plaster board wall 

This is just a quick video showing how to patch 3 different types of holes that you might encounter in a plaster (Gyprock) wall.
I mostly made this video as I haven't really found a good description of using the fill-in patch online.
The type of patch you want to use is mostly dictated by how big the hole is: Anything under 12mm or 1/2" you can just fill directly, anything up to about 50mm or 2" can be fixed with plaster tape, and anything bigger than that should be filled in with a piece of plasterboard.
Some tips:
Don't be afraid to make the hole bigger to make it a more suitable shape.
Make sure you force the first coat of stopping compound into the holes and be aware it will sink as it dries.
When sanding don't sand through the fiberglass plaster tape.
If you have a larger round hole (from a down - light for instance) you can use a hole saw to easily create a fill-in piece.
