The pilot is the last line of defence in these situations. If, for whatever reason, the pilot doesnt call in fatigued, then the good old swiss cheese holes are lining up. The onus by way of law is for the company to implement a FMS, putting the onus on them. If that FMS is not working then the company/pilots need to talk to CASA as they rubber stamp, oh sorry, approve these matters. The company WILL work to within a bee's dick of its approved limits. Ayone who thinks otherwise is dillusional.
