How ATS Résumé Checkers Work in Australia (and Their Limits)

At its core, an ATS is a database with a search function. When you apply for a role, the system stores your résumé and usually tries to extract text from it — your name, contact details, work history, and other content — into structured fields. Recruiters and hiring managers then search, filter, and sort applicants within that system, often by keyword, location, or years of experience.

• Stores your application alongside everyone else who applied
• Attempts to extract text and sometimes structure it into fields
• Lets recruiters search and filter applicants by criteria they choose
• May support automated screening or rejection rules configured by the employer

Different employers also use these systems differently. A small business might use a basic version mainly to collect applications in one place, while a large organisation might configure detailed filters and automated status updates. Because the setup varies so much between employers, it is not possible to describe a single, universal way these systems behave.

Parsing is the process of converting your résumé file into text the system can store and search. This generally works best when a document has a simple, linear structure: a single column of text, standard section headings, and plain formatting. Parsing tends to struggle with documents that rely heavily on visual layout to convey meaning, because the extraction process reads text in a way that does not always preserve position on the page.

A heading like this, placed on its own line with a consistent style, is easy for most extraction processes to identify as the start of a new section. A heading embedded inside a decorative graphic, or placed inside a table cell alongside other content, is far more likely to be read in an unexpected order or missed altogether.

Since exact parsing behaviour varies between systems and no two platforms are identical, the safest approach is to use formatting choices that are easy for any text-extraction process to follow, while still being easy for a human to read.

• A single column layout rather than side-by-side columns
• Standard section headings such as Work Experience and Education
• Plain bullet points instead of icons, images, or text boxes
• Dates written in a consistent, simple format throughout
• A résumé saved as a standard file type such as PDF or DOCX

It is worth testing your own résumé by copying its text into a plain text document. If the content comes out in a sensible order with sections still identifiable, that is a reasonable sign the document will extract cleanly elsewhere too. If the text comes out jumbled or missing sections, it is worth simplifying the layout before you apply.

Many job ads list specific skills, tools, or qualifications. It is reasonable to use the same terms the ad uses, as long as they genuinely describe your experience — a recruiter who searches for "Xero" or "forklift licence" should find you if you actually have that experience, described in familiar terms rather than only a synonym.

• Mirror the exact terms from the ad only when they are accurate
• Avoid repeating a keyword many times with no real content around it
• Spell out both the acronym and full term at least once, for example "Working With Children Check (WWCC)"

Keywords work best when they sit inside a real sentence describing what you did, rather than listed in isolation. A line that reads naturally is useful to both a search function and a human reader, while a dense list of unexplained terms tends to look like it was added only for a system rather than for the person reading it.

Because ATS platforms vary widely, and because recruiters configure searches differently for every role, no tool can see inside every employer’s specific system or guarantee how your résumé will be read in it. Any guide, course, or piece of software that claims it can guarantee your résumé will be read, shortlisted, or scored above a certain level is describing something outside its actual knowledge.

• Hiding keywords in white text or tiny font, which looks dishonest if it is ever read by a person
• Using heavy graphics, columns, or tables that can scramble text extraction
• Stuffing a résumé with keywords that do not reflect real experience
• Saving the file as an image or unusual format that may not extract cleanly
• Believing a single formatting trick can outweigh a lack of relevant experience

Use this list to check your résumé is easy to parse and honestly written before submitting it through an online application portal.

• Single column layout with standard, clearly labelled section headings
• No reliance on text boxes, icons, or images to convey key information
• Relevant terms from the job ad appear, and only where accurate
• File saved as PDF or DOCX, with a clear, professional file name
• Dates and job titles are consistent and simply formatted throughout
• I have not added any claim purely to match a keyword
