Free Standing Deck Bracing. We recommend installing diagonal knee braces to help support decks that are over 10' high. There are no specific requirements in nzs.
2x6 diagonal vertical cross bracing may be provided in two perpendicular directions for freestanding decks or parallel to the structure at the exterior column line for attached decks. Drive no less than two 16d galvanized nails through the brace at each floor joist. I can speak from years of experience that free standing decks can be built extremely strong easily up to six or seven feet high.

If not then knee braces both directions on all four corners would be appropriate. The deck will be about 6' above the ground. When the deck boards are installed it will be even more solid. First off, diagonally brace the platform itself, either with diagonal decking, or with a 1x or 2x fastened diagonally across the bottom of the deck.
