Harry is a permanent resident of Australia. He was born in Thailand, and he maintains his Thai citizenship. Harry spends most of the year working off East Timor's coast on Salmon Farming for a company. He was recruited for this job in Australia and signed a contract with the company in Sydney. For the last six years, his wife has lived in Australia with their three children. They purchased a home in Australia three years ago. Harry and his wife have a joint account with Commonwealth Bank. Harrys children attend public school in Australia. Harrys salary is paid directly into this account. All his family other investments, including a share portfolio that generates dividend income, remain in Thailand. Harry gets one month off from work every third month and, on these occasions, he meets with his family either in Australia or on holidays in Thailand (to visit his parents).
