I was recently at an airport ( Brisbane Airport) accompanying my father who's about to depart the country for business reasons. As the airport recently went through some renovations, the self-service system was chaotic. My father bought an e-ticket online where it specifically stated that he can bring two large luggage that weigh 23kg each. However the airline (which I will keep anonymous) service desk stated we can only bring 30kg in total, with extra charges applied to the extra weight for our luggage. He directed us to the sales desk to sort out this problem. However, when we went to the sales desk, the staff said he wasn't in charge and ask us to line-up again at the airline service desk. When my father tried to reason with him, asking for guidance and explanation, the staff's attitude was patronising (by repeating his statement over and over again in hopes of shutting my father up) and extremely rude and ignored any of my father's wishes (despite him acting reasonably calm and collected). Since this was obviously going nowhere, I openly started voice recording the conversation (which I was also a part of) using my smart phone. My intention was to record his words, so that when we go to the service desk again, we don't need to come back to the sales desk again. However, the staff immediately removed my phone without my consent, asked me to remove the file (in which I did because I don't want any legal trouble). When we decided to put this behind us and line-up again in hopes of sorting the luggage out, the staff came to us. Although he did offer to take the luggage free-of-charge, he took my details (from my drivers licence which I consent to because, once again, I don't want any trouble), and said he can and might take it to the Australian Federal Police (because I recorded him without his consent). Although he did say that he will not press charges, I am still concerned that he might change his mind. I looked up some Queensland Privacy Laws, in particular INVASION OF PRIVACY ACT 1971 - SECT 43, and it said that as long as I am a party of the conversation, it is my right to legally record it. So, did I actually unlawfully commit a crime? Did this staff breach any laws? I am not asking this to press charges against this particular staff, I am wondering this to protect myself as a consumer of this particular airline. Thank you.
