Its not the posts that I find are the first casualties its the panels
themselves.

Depends on how the fence is done.

Also whether metal concreted or wood directly concreted, after time the
post shrinks and swells and water gets down into the bottom of the post
hole in the concrete, it cannot get away, rusts the sockets and rots the
wood and the break occurs at ground level usually.

He's talking about posts in metal and is asking about the size of the posts.

make damned sure the wood is well protected al the way down and if
possible impregnated as cheapo posts tent to break.
Can you run to concrete posts?

Hi, oh learned ones!

I need to construct a fence that will be subject to some strong winds.
It is only 5.7 meters long and will have 5 posts, two of which will be
bolted to buildings. The three intermediate posts will be held by
galvanized fence post holders (concreted in). My big question is: Is
there any point in stretching to 4" posts and hardware, or will the 3"
versions be perfectly adequate? I find it hard to imagine a 3" fence
post snapping in even the strongest winds - but I could be wrong.

Any insights or advice on this matter?

Many thanks

PS.. I forgot to mention that the fence will be 2 meters tall and all
timber.

3" definitely not enough! 4" minimum unless you enjoy replacing broken
posts. ;-)
