If your travel was for 6 consecutive nights or more, the ATO requires you to keep a travel diary.
In your travel diary, record the details of each business activity as you go, including:
- the nature of each business activity
- the date and approximate time the business activity began
- how long the business activity lasted
- the name of the place where you engaged in the business activity.
The travel diary can be in any format that records this information.
