求翻译：The first migrants arrived in Australia after a long voyage on small sailing ships. Life was very tough at first because they did not have adequate equipment of food. One of the first things they did was to dig the soil and sow vegetable seeds. However, it wasn’t easy to grow enough food for everyone and in the first few years they faced starvation. Despite all the hardships of those early years, many of the migrants succeeded in building a good life for themselves. Within a reasonably short time some had established large sheep farms and began to export meat and wool back to England. We know a lot about these early years of Euroupean settlement beacause most migrants corresponded with their families at home and many of their letters still survive. These early settlers owed their survival to hard work and determination to succeed.是什么意思？
