Need Advice - Finding a job

I am a chemical engineering graduate who is looking for a job in Australia. I am seeking advice for what to do now.

It has been nearly a year without any responses. I have tried applying online and some cold emails. Yet none worked.

Should I just try applying more?

What do you suggest for an effective cold email, cover letter template?

I have seen a few posts talking about cold emails, yet not all positive.

Thank you!
