The present invention relates broadly to a fluid coupling assembly (10) comprising a fluid nozzle sub-assembly (12) arranged to releasably couple to a fluid receiver sub-assembly (14). The fluid nozzle sub-assembly (12) includes a nozzle assembly body (16) defining a pressurised and upstream fluid passageway (18) having a fluid discharge opening (20), and a sleeve (22) slidably mounted to the nozzle body (16) and arranged on sliding movement for opening of the fluid discharge opening (20). The fluid receiver sub- assembly (14) includes a receiver body (26) defining a downstream fluid passageway (28), a hydraulically-actuated poppet valve (30) mounted within the receiver body (26), and a receiver poppet valve (48) including a receiver poppet (54) mounted within the receiver body (26). On coupling of the nozzle sub-assembly (12) to the receiver sub-assembly (14), the following steps occur: 1. the receiver body (26) abuts the sleeve (22) displacing it axially relative to the nozzle body (16) exposing and thus opening the fluid discharge opening (20) permitting fluid to flow through the upstream fluid passageway (18); 2. the fluid flowing through the upstream fluid passageway (18) enters the downstream fluid passageway (28) hydraulically actuating the hydraulically- actuated poppet valve (30) to open it wherein the fluid flows through the downstream fluid passageway (28) exiting the receiver sub-assembly (14).
