Welcome to the Bunnings Workshop community @firenevac. It's great to have you join us and many thanks for your question.
The Matrix Decor panels can be screwed directly to the Colorbond fence posts and rails with Buildex 12-14 x 35mm Climaseal Hex Head With Seal Cladding Tek Screws 5 Pack. Depending on the height at which you want to fix the Matrix panel, you might find there is no top rail to screw into and just the Colorbond sheet. If this is the case you can fix strips of timber between the Colorbonds upright posts and then screw the panels to the timber.
Here's a helpful step-by-step instructional video on installing the Matrix frames which I trust you'll find useful.
Please let me know if you need further assistance or had any questions.
You stated The Matrix Decor panels can be screwed directly to the Colorbond fence posts and rails with Tek screws. I have the assembly screws, which requires you to drill a 12mm hole in the decor panel for expansion & contraction. Do I use these assembly screws instead of using the Tek screws? What I was going to do, was follow the instructional video on installing the Matrix frames, but instead of a wall, installing on colorbond fence. A couple of weeks ago, I found a photo of a back fence of colorbond with one sheet of Matrix Decor Screen attached to the fence, but despite searching the net, I cannot find this photo again.
Could you please advise.
Just wanted to let you know that @MitchellMc will be back on the site tomorrow to assist you with your fencing project.

The screws I mentioned, Buildex 12-14 x 35mm Climaseal Hex Head With Seal Cladding Tek Screws 5 Pack, are self-tapping and will drill their own holes. The screws included in the kit are not self-tapping and will require a 4mm pilot hole as per the installation guide.
Bear in mind that if you don't install a mounting rail and instead screw the Matrix screen directly into the fence panel, then the screws will penetrate out the other side of the fence.
Another option to avoid screwing into the fence would be to drive a post on either side of the panel into the ground directly in front of the fence. The Matrix screen can then be screwed to the posts.
Please let me know if you need further information or had any questions.
