How are you fixing your noggins? They might need to be staggered.
What’s the thinking with your end design? It looks like extra weight and complexity to me for minimal benefit (and cutting/fixing it will be a pain) - if it’s stiffness, a 200mm overhang isn’t going anywhere in 2x5 timber, especially once the deck boards are on to tie it all together.
Depending on how you’re fixing the noggins, I would move the inner four posts out slightly so they’re attached to the main joists, which will make it easier to build.

Was going to toenail the noggins in but equally happy to stagger them and use screws .
Reason behind the extraness at the sides is to provide fixing points for the picture frame deck boards and a second board to provide fixing point to the ends of each main deck boards. I just quite like the look of a mitred border and its the best option I could come up with to allow me to fix them.

Anyone have any opinion on this deck foundation layout? Top of deck is 200 - 250mm above ground level. Intention is to use C16 2x5's and 100 x 100mm PT fence posts in concrete. I'd like to do as little fence post digging as possible...
