    Working in Marine Biology or Science

    Marine Biologists can gain employment in both government and non-government agencies.  There is high competition for jobs at this level as they are not extremely common.  However, if a Marine Biologist has varied experience and formal studies it will increase their opportunity of finding a job as they can apply for a wider range.  Possible occupations include:

    Field Researcher Aquarium Assistant Ecotourism Expert Guide Marine Park Manager Lecturer/Tutor Marine Planner Environmental Consultant Where could you Work? Government Agencies Ecotourism Tour Operations Universities and Colleges Private Sector (eg. marine resource companies) Aquaculture Farms Self-employed (eg. Consultant) Aquariums Pet Shops, Aquarium suppliers Wildlife Conservation Organisations

    Remuneration in the marine sciences industry can vary greatly but most full-time positions earn an average salary. Managers or specialised positions (i.e. Environmental Consultant, Planning Manager) can earn a comfortable salary but it may take some time and experience for advancement.  Rates of pay can be low for people starting out (irrespective of whether they have a qualification or not), but those who have formal training and can demonstrate useful skills, are likely to advance faster than others.

    Risks and Challenges
    Probably the main risk and challenge of becoming a marine biologist is the competitive nature of the industry. Once you have obtained work, much of the stress acknowledged by Marine Biologists in the field is in organising schedules. When working in the tourism industry stress can become a factor when coordinating groups of visitors in the water. 

    There are also inherent risks involved when working in the marine environment, especially if you are constantly working in the ocean collecting data. 

     

    How to become a Marine Biologist


    When starting out in this industry it is beneficial to offer your expertise as a volunteer with either government or non-government organisations.  This not only gives you experience which is so highly desired by employers but also access to an organisation which you wish to work for in the future.
     
    Varying your skills can also set you apart and broaden your opportunities for further employment.  It is good to have a speciality, however this can be limiting when looking for work.

     

    To work as a contractor in this field, you should consider personal indemnity insurance. A Professional Indemnity policy aims to shield the professional's assets in the event of a claim, therefore ensuring that he/she is able to carry on their business. Most of the roles mentioned above are not filled by contractors and are more commonly recruited as casual or permanent positions. To minimise risk of liability, you must investigate and learn about the legal and professional requirements for practicing in this field.
     
    To become a Marine Biologist you will need at least three years undergraduate qualifications and most likely either a Masters or PhD.  However, if you would like to start out in this field or try it out before committing yourself to full-time study, you can look to complete vocational courses.
     
    There is also scope for working as a guide, or similar in a marine environment without a University qualification, such as a snorkel guide, whale watching guide, scuba guide, whale shark spotter and guide etc.

    Related areas of employment can include:

    • Aquaculture
    • Wildlife Officer
    • Park Ranger
    • Animal Rescue
    • Zoo Keeper
    • Scientist
    • Wildlife Observation
    Member of Study Gold Coast Education Network.

    How can I start this course?

    You can enrol at anytime and start the course when you are ready. Enrolments are accepted all year - students can commence study at any time. All study is self paced and ACS does not set assignment deadlines.

    Please note that if a student is being assisted by someone else (e.g. an employer or government subsidy), the body offering the assistance may set deadlines. Students in such situations are advised to check with their sponsor prior to enrolling. The nominal duration of a course is approximately how long a course takes to complete. A course with a nominal duration of 100 hours is expected to take roughly 100 hours of study time to complete. However, this will vary from student to student. Short courses (eg. 100 hrs duration) should be completed within 12 months of enrolment. Certificates, Advanced Certificates and Awards (eg. over 500 hours duration) would normally be completed within 3 -5 years of enrolment. Additional fees may apply if a student requires an extended period to complete.
    If a student cannot submit their assignments for 6 months to ACS, they should advise the school to avoid cancellation of their student
    registration. Recommencement fees may apply.

    We recommend that you are able to browse websites, send emails and conduct online research. You will need to be able to type and submit your assignments.
    If you have limited computer skills, we can make special arrangements for you.

    This is possible, it depends on the institution. We recommend that if you would like to use our courses that you contact the institution first. Our Course Handbook is a good resource for this.

    Our courses are designed to build knowledge, hands on skills and industry connections to help prepare you to work in the area, running your own business, professional development or as a base for further study.

    This course has been designed to cover the fundamentals of the topic. It will take around 100 hours to complete, which includes your course reading, assignment work, research, practical tasks, watching videos and anything else that is contained in the course. Our short courses are a great way to do some professional development or to learn a new skill.

    It’s up to you. The study hours listed in the course are a rough guide, however if you were to study a short course (100 hours) at 10 hours per week, you could finish the course in 10 weeks (just an example). Our courses are self-paced, so you can work through the courses in your own time. We recommend that you wait for your tutor to mark and return your assignment before your start your next one, so you get the benefits of their feedback.

    The course consists of course notes, videos, set tasks for your practical work, online quizzes, an assignment for each lesson (that you receive feedback from your tutor from) and ends in an exam (which is optional, if would like to receive the formal award at the end), using our custom built Learning Management System - Login.Training.

    Our courses are designed for adults to gain professional development and skills to further their careers and start businesses.
