There are three different Australian student visa types-

Student Visa (Subclass 500) – This visa will allow you to take up a full-time course in Australia and live there for up to 5 years Student Guardian Visa (Subclass 590) – If you wish to support a student who is under 18, you will need to apply for this visa Training Visa (Subclass 407) – Allowing you to do workplace-based training, this visa will allow you to participate in a classroom-based professional development training program and stay in Australia for up to 2 years

If you’re studying in Australia for up to 4 months, you could get a Working Holiday Visa.

Most probably, if you have a degree from an Australian university you will be eligible for a post-study work visa.
For that...
What I would recommend is for you to start creating a strategy to achieve your goals

Research your industry in Australia.
Research what companies are looking for in an ideal candidate. And then start gaining experience in the Australian market as soon as possible.
Internships and part-time jobs in your industry are an excellent idea.

The cost is AUD 620 + AUD 460 (if 18 and above) or + AUD 150 (if under 18)

Also-

Your academic transcripts Degree certificate, and A letter of statement from the university that has admitted you

29 to 42 days for students who want to pursue higher education in Australia

Yes, you'll need a student visa

Because students who don't need a visa for NZ have to satisfy one of the following categories-

You are a citizen of New Zealand or Australia If you are a resident of New Zealand You have a permanent visa for Australia

If you’re planning to live in New Zealand after graduation, it’s best to get a job in an occupation where there’s a shortage of skilled workers.
You will find a list of Essential Skills in Demand on the New Zealand government website.
Doing this will definitely improve your chances of getting a residence visa later.

Your student visa will be valid for the same length of time as the study you’ve paid for.
This means that, if you want to stay back, you will need to land a job before you graduate and get a post-study work visa before your student visa expires.

If you want to apply for a visa, the first thing you need is an acceptance letter from the university you have applied to. The visa application needs a letter of acceptance, without that you won't get visa approval. After that, you can start your visa application by downloading it from the website of the Australian High Commission/Consulate available in your country. Apply at DIBP's online system for your visa application. You have to apply at least 12 weeks before the start of the academic year. The application fee is around the AUS $656. You might also have to go through a medical examination and a visa officer will take your interview. You have to be very honest with your answers otherwise your visa might get rejected. It usually takes 2-3 months but it may take more time so, apply accordingly.
