I have been invited for an interview for a lecturer position at a university in Australia. I am based in Europe at the moment. It is not expicitly clear, at least to me, in the invitation email that they will pay for the travelling and accommodation expenses, whether in full or in part. I thought I should ask them for clarifications, but I am not sure how to ask it, and perhaps it is better to find out more about the custom before asking.
The short answer is 'yes'. I know some colleagues who were invited for an interview for a lecturer position at an Australian university and they were indeed reimbursed for all their travel+accommodation+food+visa procedure expenses for the trip. The reimbursement was not conditional on if they would accept the job if offered or not. It was also written clearly on their invitation letters (needed for their Australian visa application) that they would be reimbursed all these expenses. However, you must NOT assume anything. It is going to be a good amount of money travelling from Europe to Australia, and you must clarify about your reimbursement.
