I've got 2 minor cracks in the ceiling (bathroom & loungeroom) but the worst is this hallway crack (photo attached).
I would like a permanent fix if possible. I noticed a very similar Bunnings post and I liked Eric's suggestion of installing an expansion joint first.

Should I get a roofer to come out first and do this, or is something that the plasterer can do?
Please advise if you have any other suggestions.
My house inspector at the time mentioned that it was caused by extremes of temperature.
The rest of the house looks fine, for a 1980s house.
Thank you.
