A decking system comprising: a plurality of joists spanning in parallel, spaced apart from one another so as to be arranged to support a plurality of deck boards spanning transversely across the plurality of joists; and a ledger board spanning in a longitudinal direction transversely across a mounting end of each of the plurality of joists such that the plurality of joists are supported on the ledger board at spaced apart positions in the longitudinal direction of the ledger board; the ledger board comprising: a first side and a second side opposite one another and extending in the longitudinal direction of the ledger board between respective ends of the ledger board; an upright portion formed at the second side which is arranged for mounting against an upright supporting surface; and a plurality of ledger board joist connectors formed at the first side of the ledger board including at least one ledge portion which protrudes from the upright portion; the mounting end of each joist comprising: an overhang portion extending in the longitudinal direction of the joist beyond a remainder of the joist, the overhang portion being supported on said at least one ledge portion of the ledger board; and a hook portion which is hooked onto the ledger board between the first and second sides of the ledger board by interlocking engagement with a respective one of the ledger board joist connectors so as to prevent movement of the joist in the longitudinal direction of the joist away from the ledger board; wherein the hook portion of each joist extends downwardly from the overhang portion of the joist and the ledge portion is spaced outwardly from the upright portion at the second side of the ledger board such that the hook portion is received between the ledge portion and the upright portion at the second side of the ledger board.
