Hello @Curiousnewbie
Welcome to the Bunnings Workshop community. It's sensational thar you join us, and thanks for sharing your question about attaching a door to your shed.
That is a bit of a challenge, technically a frame would have to be built inside your shed and anchored to the concrete floor in order to accommodate the door jamb of the door. I suppose you could just use angle brackets to attach the door frame to the shed, but the problem is that the shed walls were not designed to hold that much weight. It would probably rattle and damage the shed wall in the process.
Let me call on our experienced members @Dave-1 and @Nailbag for their recommendations.
If you have any other questions we can help with, please let us know.

Good morning @Curiousnewbie
My thoughts follow along @EricL's I would frame the rear side of the doorway and attach the timber to the concrete slab with right angled brackets. You could frame up the whole shed on the inside but would probarly loose a bunch of space. I would be concerned that the added weight of a door would tear the metel shed as is.
If you are trying to make it more secure then maybe some square metal tube bracing the door diagonally would also work.
