Visited my first Mega Event today, and passed on this trackable to a couple of visiting geocachers I met at the Mega. They have taken your trackable back to Europe with them, but for some reason have not logged it as 'grabbed' from me as yet. I did not get their contact information, so hopefully they will log it soon, and you will see some logs much closer to your trackable's home and goal - London.
In the mean time I hope you have enjoyed watching the trackable's journey across the southern parts of Australia.
