I bought this Atlantis Halo SUP (11,0 x 33 x 5) new, details here: -
The package including board, paddle, ankle strap and fin was $1300, and I'm including all of these items. I can include a carry bag (with broken zip) if required.
The board has only been used 5 or 6 times, and is in excellent condition, as can been seen in the pictures. Would obviously suit pickup in Sydney, but happy to arrange courier delivery if those costs are met.
