We moved here from the UK in 2013 and are currently completing the citizenship application online lodgement. I have reached a question that asks me to state all overseas travel outside of Australia from age 18. To include work, holidays etc. It requires dates from and to...how on earth can I remember exactly when I went on holiday 20 years ago?! My husband will have even more problems as he frequently travelled on business from the UK all over the world, several times a year. How have other people tackled this section?
