If you are in Europe, I imagine that will include the UK. When you get to the UK, register with a GP. To register with a GP you will probably have to ring around as some don't take new patients, perhaps mention you are a travelling T1. Anyhow, you usually have to have a meeting with a nurse before a doctor.
BUT they give you this card .... and scripts for diabetics in the UK were free! I got free insulin, free BGL strips!! Mind you this was 6 years ago, so things may have changed.
When I first moved to UK and then to Netherlands ... I took letter from Endo, and scripts. I also left scripts with family incase. If all else fails head to an emergency department. Australia has quite good reciprocal arrangements with other countries if you get into a fix.
Also good info on websites...http://www.diabetesvic.org.au/living-wi ... althcareOS
Have a fabulous trip!!
