I am building a wooden shed in the backyard. It will be a wooden floor and stud wall. Do I need put a damp proof of some description between the wooden floor and the base plate of the stud wall
Welcome to the Bunnings Workshop community @Bluey65. It's sensational to see you make your first post after being such a long-standing member.
Could you provide a bit more information on how you’re building the shed floor and walls, and where the floor will sit relative to the wall base plate? Do you have any plans or sketches? Is this on posts or a concrete slab?
Typically, you’d place a dampcourse/DPC between the timber base plate/frame and the concrete slab or footings to stop moisture wicking up into the timber. If that’s already in place, there generally wouldn’t be any need for another layer between the floor and the base plate.
You want to prevent moisture getting into the floor as the priority. Then, everything above that shouldn't experience moisture.
Looking forward to hearing more. Please let me know if you have any questions.

Let me also tag a few members who have previously discussed timber shed builds such as @DanUnited, @hjt1701, @J48 and @Bruce129, to see if they have any advice on your project.
the floor will be raised above the ground. The wooden floor will be made like a deck.
So the stud wall will be attached to the wooden floor and
Ideally there should be no moisture movement into your underlying frame as that moisture would migrate from the frame into the flooring @Bluey65. It's best to stop it before it gets there. If for some reason water would be in the floor structure, then yes, you should and a dampcourse layer between the baseplate and the flooring.
