Hi @Arwen,
Welcome to the Bunnings Workshop community, it is fantastic to have you with us.
It would be difficult to go into too many specifics in terms of the best method of removing the wall without seeing it, so I'll wait to see what you are working with before going into too much depth.
In saying this, the first step with any wall removal is to confirm that the wall is not supporting the roof in any way. If it is a dividing wall inside a wardrobe then it is pretty unlikely that it will be, but it would be best to have an experienced person such as a builder, engineer or qualified carpenter it to confirm this. They will likely get into the roof cavity to inspect how the roof framing sits in relation to this wall.
There is a possibility that this wall is bracing the front wall of the wardrobe, but once again, it would be difficult to say without seeing and inspecting it, so it is probably worth having an experienced person inspect it.
If you can confirm that the wall is not supporting the roof in any way and that it is not bracing the front of the wardrobe, then the process is pretty simple: start by removing trims and mouldings, then remove the plasterboard or sheet products to expose the framing. Once the framing is exposed, you'd cut the studs with a reciprocating saw and detach them from the top and bottom plate, then remove the top and bottom plate.
If you work piece by piece, it is not overly dangerous as long as you think logically and wear your protective equipment. I'd suggest gloves, long protective clothing, enclosed shoes (preferably steel cap boots), eye protection and a mask.
Have a look at How To Remove a Stud Wall for further guidance.
Once you can provide further details, I'll be happy to assist further.
