Yeah Id put 4x4 H3 treated posts in behind the concrete wall, 180mm below the top of the bricks, then put a 180x25 long ways on top running parallel with the wall, this will leave the back half of the posts exposed so you can run your joists off them..
Since you don't have to back full to much have you looked into the support pads to hold joists?? sort of like the Nurajacks.. I think mitre 10 (and maybe Bunnings) do something similar.. if it was me id put a paver under each one to help expand the weight.
