Arrived safely, eventually, although the tracking was a bit iffy. Grandson is pleased which is the main thing.
The carrier is a bit suss. They had marked it delivered, but nobody had seen it. I tried chasing it up and was told, they sometimes mark it as delivered when it reaches Australia and changes carrier but it turned out it HAD been delivered on the original date I was told ( which was about a week earlier than expected) ,BUT IT HAD BEEN THROWN UP ONTO THE BALCONY OF AN UPSTAIRS ROOM WHICH NO ONE SAW FOR ABOUT A WEEK!!
As this was quite an expensive item I suggest using a different carrier in future.
