Hi, first time posting. I will be traveling to Perth later in the year from Heathrow. I am type 2 but take insulin as well as Metformin and other medication in tablet form. I will get a letter from my Diabetes Sister that's no problem. I will need to take at least 2 boxes of 5 pens and my mobile testing device which I can carry in my hand luggage. Will the boxes need to be put inside the clear plastic bags?
