Hi @kylahhh,
Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you with us.
It looks like you've got a vinyl-wrapped hollow core door. Does the surface feel soft, almost like plastic?
Repairing the door is fairly simple and you can follow this guide by my colleague @MitchellMc - How to repair a hole in an internal door.
The main issue you are going to have is that there aren't a lot of paint choices that are great over vinyl, which is essentially plastic. The White Knight Squirts Spray Paint range is good over plastic and can be used in your application, but your colour options are limited, and it would be difficult to get a perfect match in terms of colour.
It is worth a shot, but replacing the door may be your best option.
Let me know what you think and if you have any further questions please don't hesitate to ask.
Jacob
