If you have a job involving a typical fly in/fly out arrangement, it is likely your employer provides you with all of the following:
barracks-style accommodation while you are on onsite that you must vacate when you fly out
canteen meals while you are onsite
transport from a pickup (which may be a nominated airport) to and from the site.
In these circumstances, the site is not your temporary residence, so you can claim a deduction for any contribution you make to the accommodation or meals provided. However, you cannot claim a deduction for your costs of travelling from your home to the pickup point.
