UPDATE: Boxes released to my girlfriend yesterday - would not have been able to get through this without Claudia my Despachante de Aduana - some valuable lessons learnt - the rest of the stuff I will bring will come with me on the plane and I won't be trying to get anything else in until I have my paperwork sorted out down there...
As for my freight/shipping company here in Australia - they will be paying for the hell they put me through - they don't know it yet but they will...
John.
