Hello @AMB

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your telephone jack.

I suggest having a quick look at this discussion - How to remove old telephone ports? by @JonnyH. In the discussion, it was emphasized that the telephone cable be properly terminated and made safe by a proper cabler. Once that has been accomplished you can then cover the phone outlet.

I propose wrapping the cable with a clear self-sealing sandwich bag and securing it with a cable tie to protect it from moisture. I then suggest covering the opening with a Carinya 200 x 60 x 1mm Galvanised Flat Plate Make-A-Bracket. It will need to be trimmed down to cover the opening, you can then render over the opening that's been covered up.

Here is a handy step-by-step guide: How To Render

Since the repair spot is not that big, you can use a small bag of mortar to patch hole in the wall.

If you have any other questions we can help with, please let us know.
