Load restraint – it is what is inside that counts - CoR laws and HVNL liability

The Chain of Responsibility (CoR) laws require that any goods loaded on a heavy vehicle are properly restrained. For any goods not properly restrained, any person concerned with the packing, loading, securing or carriage of the goods can expect to be held liable under the Heavy Vehicle National Law (HVNL). 

But, the load restraint requirements don't just apply to the goods as loaded onto a heavy vehicle, they also apply to the restraint of goods within a freight container, which is usually done at the point of origin and not visible or able to be inspected by any party further down the chain. So, how do you ensure that you are discharging your obligations in relation to the restraint of goods within a container when you didn't pack the container and can't check the load restraint within it once the doors are sealed?
