If you are running a business and have travelled in Australia or overseas on the business trip then you can claim the deduction for the expenses you have incurred.
However, if you are looking to start a business and travelled on the research purposes then you would not be able to claim a business deduction.
If you are staying away from your resident place of business for six or more consecutive nights then you must use a diary to record the particulars of each business activity.
The particulars would include
• The nature of the activity
• Day and approximate time of the business activity began
• How long the activity lasted
• The name of the place where you were engaged in the business activity.
You must exclude your business and private expenses on your business trip.
