My wife and I are planning to take an overnight Eurostar trip to Paris whilst staying in the UK in May. I am travelling on an Australian passport and understand I don't need a Schengan Visa to do this. However my wife will be travelling on a Kenyan passport. I have read that if the travel documents were issued in Australia (as we will book it online from here) she will be exempt like me. Is this true? or do we have to go through the expensive process of getting a Schengan visa for her for a one night stay in France?
