To send as "small" (?) parcel you are allowed up to 32kgs.. I sent a suitcase over to Australia weighing EXACTLY that, by air, and it cost £145
I sent a Genlock to Aussie weighing around 5kgs and it cost £35 (iirc ..no more than £40) to someone on this very site !!
Probably cost you around £60 .. How is she going to package it is the big question ... you really dont want it to have a snapped head when you receive it !!
