How to brace a colourbond fence that wobbles

Hi All

Our backyard colourbond fence located on a busy road and it wobbles when cars drive pass it and when it is windy as well.

It's colourbond and with 8 posts concreted in but the whole length of fence (7 panels x 2.3 = 16m) does like a wave as the wind hits it.

I bought two star pickets 2400mm similar to those ,,,temporarily support

The fence is screwed to a timber boards on ground as can be seen on the attached pictures and they rotted

How can I brace it properly to avoid its falling ?

Thx

Although have uploaded photos I can't see them ,,,,,I have attached a link to the photos as well

Any bracing would be temporary in nature.
Adding a diagonal (nominally 45-75-ish degrees) support from the ground to somewhere along the top third of each post will certainly stiffen it up.
Screw the top end directly into the post with some self tapping sheet metal screws. I would also add some stakes at the ground end of each support roughly perpendicular to the angled support and screw through these into that angle support so that they are fixed to the ground.

The first thing you want to do is check how large the concrete blocks are that were poured around each post.
Some fence contractors skimp on the concrete and the fence doesn't have a lot of strength. You may be able to add extra concrete at strategic places if it's lacking
