Examples of what makes a good cover letter versus a bad one - SEEK Career Advice
The cover letter is often the first element of your job application that your prospective employer will read, often ahead of your CV. A poorly crafted letter that fails to clearly articulate why you are the ideal candidate for the role, or one containing bad grammar and spelling mistakes, will result in your application getting dispatched to the reject pile. But a good cover letter can work wonders in convincing an employer of your credentials and your professionalism, as well as providing insights into your personality and character. Make sure you address the letter directly to the person named on the job ad. Describe what attracts you to working for them specifically, convey enthusiasm for their industry and show passion for their work. The next step in writing a cover letter is to summarise your main skills and experience, condensing the most compelling parts of your resume and highlighting your skills as they relate to the specific requirements of the job ad. Outline any general skills you think are relevant to the role, such as communication and interpersonal skills, problem-solving abilities and organisational strengths.
