Masters Degree: There are three main forms of Masters Degrees within the Masters Degree qualification type: the Masters Degree (Research), the Masters Degree (Coursework) and the Masters Degree (Extended). The purpose of the Masters Degree (Research) is to qualify individuals who apply an advanced body of knowledge in a range of contexts for research and scholarship and as a pathway for further learning. A master’s degree usually takes one to two years to obtain.

Graduate Certificate Once you have a bachelor degree, or can provide evidence of sufficient prior learning, you can get a graduate certificate or graduate diploma. Undertaking a graduate certificate or diploma will give you further, specialised knowledge in usually one area of study.

Depending on the course you undertake, you may extend on the knowledge you gained during your undergraduate degree or equip yourself with a different vocational skill. Individuals holding this level of qualification are regarded as critical thinkers, good communicators and problem solvers, able to process and transmit information very well. A graduate certificate usually requires 6 months, and a graduate diploma usually requires 1 year to obtain

Diploma

The skills you obtain from a diploma qualify you to work in a variety of contexts framed by established parameters. A diploma provides you with a deeper understanding of a particular area of knowledge. Diplomas teach you to communicate well with your colleagues, analyse problems that may be complex, and use your best judgement to make decision.  The duration of a diploma is 1-2 years.

Advanced Diploma: Level 6

An advanced diploma qualifies you as a highly skilled worker with specialised knowledge. It enables you to undertake skilled work, or function as a paraprofessional. A paraprofessional is someone who can complete specific tasks in a profession but who isn’t licensed as fully qualified.

Hope this clears your confusion!
