Unfortunately some water split and got into the multiboard. The surge protection saved the TV, Sonos and router etc but the power point isn't working. I found one more plug in another room that has also stopped working, but I've checked the fuse box and can't figure out what ones relate to these plugs.

Could it be something else or do I just not know what I'm looking for?

Are they older style re-wireable fuses (usually white ceramic housing) or the standard cylindrical ones (usually black plastic housing)?

Do you have a multi meter? If so, pull each fuse one by one, and check for continuity across the fuse.

If not, then turn other appliances on around the house, again pulling each fuse one by one until you reach the one which doesn't affect anything. This will be the culprit.

You can verify you've got the correct one by swapping a known-good fuse of the same current rating with the suspected bad one & the circuit should have power.

Post a photo of the fuse box.

I assume you have isolated the multi-board and are testing the wall outlet directly?

Surge protector didnt save anything, its probably just an RCD tripping out as intended. Find anything in the board with a test button and turn it off and then on again and see if things come back.

Here's the fuse box. I've also posted a box at the other end of the house. Pretty sure nothing there relates to the lounge.

I put the multiboard in the bin, it was dripping water.

So far I have done a visual inspection of the fuses. One looked blown, so I replaced the fuse, but I don't think it belongs to the plug in question.

I'll do some thorough testing tonight

Whats the RCD feeding? - Shows as off in the top image.

As others have said, surge protector on your power board won't have done anything in this situation (the issue was water on the power board, not a surge of power coming from outside the home).

Seems like a simple blown fuse to me. Your board looks a lot like mine. Don't trust any handwritten notes about what does what. In an old place like this, fuses may not be used correctly, but normally anything designated as 10 amps is an overhead light circuit, with power points being 15 or 16 amps. Try swapping fuses of equal value around to see if the power point starts working.

That RCD has tripped as mentioned previously, reset that and you should be good to go.

The black PDL circuit breaker in the lower left corner - these have a bad habit of tripping but the handle remaining in the on position, a light tap, or turn it off then on may prove this is the problem. The black fuse marked submain could also be blown, the only way to check is with a multi-meter set to ohms and check the fuse (not the terminals on the fuse board but the top removable piece with the fuse in it).

The PDL circuit breakers also have a bad habit of never been able to be reset (the came out in the 80's and are now over 30 years old) other than that your best bet is to get your electrician out to check it out.

they came out in the 70's, ive seen a lot of house in my area built in the 80's with these, and in the pictures you can see the green goo oozing from the cables which is another giveaway of 80's TPS

Bare earth wire is a bit of a giveaway as well

I was under the impression that green goo and bare earth was a bit earlier than that. I've redone a bunch of late 80s stuff that had insulated-earth TPS in perfect condition.

60s-ish I thought for green goo.

Our house was built in 1962, probably one of the earlier houses in NZ with TPS, there's no green goo.

As a general note, that power board... shudder. Get it replaced. It'll cost $500-$1K depending on how much other remedial work they have to do to bring things up to scratch, but get it replaced.

What @Mehrts said, but also...

When you figure out which fuse goes with which circuit, label them! One day your future you will thank the present you.
