I may be wrong but I don't think this is a Beaconfield-specific question. This is a question of simple entitlement and not availability. Again, I may be wrong but, I'm pretty sure you that if you are otherwise entitled (eg you're married etc) and the duration of the assignment is greater than 6 months (?) you're onto a winner as, even if there's no MQs available, they should find you somewhere within your entitlement (eg a hiring). You may wish to try the RHQ forum for better advice.
