Over the last 10 years I went overseas about 8 to 10 times a year for work , visiting family etc. Mostly long weekends. I spent a long time digging up old emails, diaries , etc to get the dates. I'm sure if the dates are out a little it doesn't matter as they want the just of your lifestyke. I filled the travel part on the partners visa application and now have to fill it all again on the form 80. The repetition is annoying .
