In Australia, internal stud walls are typically framed with 90mm x 35mm or 90mm x 45mm timber, with stud spacing generally 600mm. Noggins (lateral support) are often placed between studs every 1350mm. Top and bottom plates are typically 90x45mm, and can be doubled for load-bearing walls or when supporting floor members. 90mm x 35mm will be fine.

Ask here about fasteners to secure bottom plate to concrete such as dynabolts.

The bottom plate needs to be sealed with something like this:

Hi @Sedg,

A warm welcome to the Bunnings Workshop community, it is fantastic to have you with us.

Check out How To Build a Stud Wall, which details how to build and install a timber stud wall.

As @AlanM52 has mentioned, internal walls will use H2 pine in a variety of sizes depending on your needs. The wall will not technically be load-bearing as it won't support the roof, but when walls are tiled, it is usually best to use stronger materials such as 90x45 and have your studs spaced at 450mm centres.

The top and bottom plates should be attached to the ceiling frame and floor, respectively. The top plate can be attached to the ceiling frame with framing nails or screws and the bottom plate to the concrete using masonry anchors. Either DynaBolts or Ankascrews are good options.

As Alan has also mentioned, the bottom plate should not be in direct contact with the concrete. Attaching plascourse to the underside of the bottom plate will prevent direct contact between the two.

Once the frame is installed and in place, check out How To Plasterboard a Stud Wall for guidance on cladding the outside of the frame.

If the inside of the wall needs to be waterproofed, it would be best to engage a licensed waterproofer early on so they can advise you on any additional considerations you should take in the framing stage.

Allow me to tag @Nailbag to see if he has any advice he can offer.

Let me know what you think and if you have any further questions, please don't hesitate to ask.

Hi @Sedg 

Simply knowing how and building a replacement wall is a relatively easy project. And the link @JacobZ provided How To Plasterboard a Stud Wall is a great start.

However before you begin, please consider other potential aspects such as the following:

• The exact position of the wall taking in account cladding thickness on both sides.
• Standard framing dimensions to suit the application 
• What type of cladding on either side.
• Plumbing and electrical requirements.
• Ensuring everything is plumb
