A flow restrictor for restricting flow in an annulus, the flow restrictor comprising a body and a restrictor assembly mounted on the body, wherein the restrictor assembly is actuatable between a run-in configuration and a set configuration in which at least a portion of the restrictor assembly is radially splayed to thereby substantially restrict flow in the annulus, and wherein the flow restrictor is actuatable by fluid flow over the restrictor assembly above a threshold flow rate to actuate the restrictor assembly from the run-in configuration to the set configuration.
