'.fseventsd' is taking up 130GB of HD space (a whole bunch of <150KB files '0000001f7dcde390' etc),
Is this normal/OK/expected?
It doesn't seem OK to me.
Any advice appreciated, Thanks.

.fseventsd is the file system for notifying spotlight changes but that size does seem excessive.
you may want to trash the spotlight index and reindex that volume.

Description (per a web search):
.fseventsd is a log file of "(F)ile (S)ystem (EVENTS), logged by the a (D)aemon". Basically there is a monitoring background process ("daemon") on OS/X called fsevents which it notices whenever files are created, modified, or deleted.
So assuming it is indeed nothing more than an OS controlled log file, such a large size indicates a runaway process that is causing the OS to create the same entry (or a few of them) over and over, causing the file to grow to an unusual size.
Thanks for the reply, but doesn't seem to have helped
To be clear, I'm getting this information from an app called DaisyDisk - I am assuming it's correct,
The Mac storage information shows the space is being used by 'other'
I managed to do a Get Info on the folder .fseventsd:
(129.49 GB on disk) for 4,512,074 items
If nothing else, they should all be log files that can be safely deleted. Make a full system backup first, then remove the contents of the folder.
I deleted the files (Edit: except 'fseventsd-uuid' as this looked different to the rest), everything seems ok for now.
Would be nice to know why this happened though so it doesn't just happen again.
Thanks for you help.
Assuming the description I found is correct, then it matches up with my guess that a daemon for some process was going nuts and making oodles of log entries. What one that was/is might be able to be determined by reading some of the logs if it starts filling up again.
.fseventsd = 130GB
