Does Australia cap the study gap allowed for masters entry?

No, there is no official maximum study gap for master's entry in Australia. Both universities and the Department of Home Affairs review your gap case by case through the Genuine Student framework, so the real requirement is proving how you spent that time, not fitting under a fixed number.

General Gap Length Guidance

Acceptable Reasons For Your Gap

• Full-time employment, backed by salary slips, experience letters, or tax returns.
• Skill development through professional certifications or short diploma courses.
• Preparation for rigorous national or international entrance exams.
• Medical or personal reasons, supported by formal certificates or legal documents.

My Advice

Never leave a stretch of time unaccounted for on your CV, since an unexplained gap is what actually damages your genuine student assessment, not the length of the gap itself. Write your SOP so it maps a clear line from your undergraduate degree, through your gap year activity, to why this Australian master's is your next logical step.
