The opportunity for a Barcelona’s student to be part of a working experience in the Port Authority of New South Wales (Australia) doesn’t show up every day. I was lucky to have it, so I took it without any doubt. It was a great experience, which brought me not only work experience, but also a lot of personal growth. So, why not trying to explain in a thesis, how I felt and what I learnt about this business. This was my motivation about this project and I think it satisfies what is, for me, the main rule: enjoy doing the project, because it is the best way to give the best of each one and transmit exactly what is wanted. The Port Authority of New South Wales is a company unknown for the majority of us (It was for me before starting the experience). That’s why it is important to do a big introduction of it in the thesis before entering in more technical aspects. I have tried to explain in a way that all readers (not only the maritime sector experts) can achieve a brief idea on how the company works after reading it. But, what is the purpose for people of Barcelona knowing about the business of one Port Authority of Australia? Be able to compare it with a local one, in this case, Barcelona. That’s why after focusing on the Port Authority of New South Wales, I developed a comparison between Sydney and Barcelona. Two big cities, separated for a lot of miles, with different cultures but running a similar business. Which of these two cities has more traffic? Which applies more expensive charges? We will figure it out during the thesis.
