You can claim a deduction for travel expenses you pay where both the following apply:
your employer requires you to do your work away from your usual workplace for a short period
it would be unreasonable to expect you to return home each day, which means you must stay away from home while you are doing that work.
Overnight travel expenses include:
meals, accommodation and incidental expenses
car, air, bus, train, tram, ferry and taxi fares
bridge and road tolls
car parking and car hire fees
visa application fees, not including the cost of obtaining or renewing a passport.
If you are claiming overnight travel expenses and you receive a travel allowance from your employer, you must record the allowance as income at item 2 on your tax return.
