Ah, wonder if that's why Nyra never strayed - we had doors either end of those rooms closed when she was smaller. Weird!
Re: diameter, checked with tape and I have three sizes for different things. In left photo it's not clear but conduit either side of switch is different sizes. Upper is 13mm as it's covering standard power cord, lower is 7mm over flat wire. I also use 16mm for covering a combo of both types elsewhere, and 13mm again on TV co-axial. TBC...

7mm is good for any flat wires (eg.. transformer lead to digital piano) and 13mm is my go-to for most bigger stuff..
I got split tubing cos it's easier to fit over (though can still be a PITA!) and for things like piano transformer wrapped electrician's tape around the very end so it doesn't easily shift and expose wiring - everything else I just had the tube.
And yeah, about $8-10 for 3m, depending on diameter, at Bunnings. All the best with it!
@imalcolm @NanoRaptor @mnemonicoverload Guess what I’m trying to repair tonight, and why!!!!
(Say hello to Cowboy, his blindness does not slow him or his teeth down in any way, and his ears are up because Violet is having a sleepover and it is Taylor Swift high volume madness right now)
@cabel @NanoRaptor @mnemonicoverload
Oh noooo! Such a familiar sight - good luck with it!
And hi Cowboy! Meet Nyra! - the reason for all the conduit covering wires at our place...!
