If you have any plasterboard cut a piece out roughly the size , either glue or fix with filler and finish it off when it's set hard.

there's not anything to hold the structure.
A hole that big there are two ways to go about it.
One get some mesh tape which you place over and it acts in a similar way to rebar on reinforced concrete. only you're using plaster instead of concrete
Two, and this one is possibly better given this is on a ceiling. Get some plasterboard, cut out a section bigger than that hole. then use it as a template to cut out the ceiling in the same size. Use a Stanley knife and thin jabsaw to minimise kerf. You now have a patch for the hole. Cut a strip baton of wood longer than the hole, put it in the ceiling and rest either side of the hole, screw into the plasterboard through the baton so it is secure then screw the plasterboard patch to the ceiling, secured onto the wood, this keeps it level with the existing ceiling. Plaster over, filling gaps and leveling to the ceiling plaster level and sand off.

This is the answer, OP. If you want to do this job yourself without using plaster, I’d recommend replacing for Pollyfilla deep fill. It’s a lot easier to use than plaster.

You could sand out the hole a bit, get some thing mesh and cut into a circle shape a little smaller than the hole, then poly fill over that? Alternatively, you can get some mesh tape? That might be a bit more plush and work better. Not an avid DIYer but like to solve problems. Hope this helps.

You need a lightweight filler. Something like this https://www.screwfix.com/p/no-nonsense-lightweight-filler-white-500ml/75073
We had terrible trouble trying to fill a ceiling hole until we got a lightweight filler. The stuff is magic. Plus it sands and paints very nicely.
I'd dig out what you've put in already and have another go with the lightweight. Put in slightly too much and then sand it down when it's dry using a sanding black so you get a flat surface.

This is the way. When you pick up the tub you think it's empty. It's amazing stuff. Super light, no mixing, no faffing. Slap it in, get it near enough, leave it to set, sand flat with 120 grit. If you get a bit of experience with it you can put it on smooth enough so it doesn't need sanding. Apply with a thin blade, flexible wallpaper scraper. Any other way=work.

Bloody love Screwfix, didn't know they did this. Did the same in a few places but used Pollyfilla as they also do something like this, Deep Hole or something (obvs, will be a bit more pricy than screwfix), it feels like kids magic foam.

No problem. Fingers crossed it stays fixed.

Clear out that mess you made (LOL) and fill it with expanding foam, which you can then trim off and finish with filler.

There are DIY hole repair kits you can buy at some hardware stores.

Padding it with newspaper and pva glue (paper mache) would help, then you could finish it with a thin layer of filler to sand down. We did this with a light fitting hole and it worked a treat

fill it in stages. like fill it up a little then leave it to dry repeat untill you get smooth flat surface. The reason it's drooping is because you are filling too much at one time
I would chip out some of what you have done and apply filler with your finger and keep building it up.
The hole isn't too big but definitely have to build it up in stages like 2 or 3 goes at it.
For the final stage I would use a spatula to apply the last bit of filler, sand it and paint
personally I wouldn't bother cutting and filling it with plasterboard. seems alot of hassle
this filler I have used before and it works alright

Polyfilla One Fill. Job done. It’s basically air. Very light. Doesn’t slump.

Get a hole cutter for your drill a little bigger than the hole. Drill ceiling to clean up the mess, then drill a puck out from some new plasterboard so it's the same size as the hole in the ceiling. Use either a (little) foam or a batten behind to hold it in place so you can smooth over it with filler.
Your filler is shrinking because it's such a large hole and it's drying out.
WARNING Only do this if it's a plasterboard ceiling not lathe and plaster
hah yes - thanks u/crankyrecursion but the ceiling is concrete so wouldn't be happy!
Concrete? Are you sure?
Does it not have a suspended timber frame for lighting?
I wish!
