Student Visa (Subclass 500) Refusal Experiences - Please Share!

I'm currently preparing to apply for an Australian student visa, and I've noticed quite a few discussions lately about visa refusals. It's making me a bit nervous, so I'm hoping to learn from others' experiences to better understand potential pitfalls and how to avoid them. If your Australian student visa (subclass 500) was refused, would you be open to sharing your story? I'm particularly interested in hearing about what course and institution you were planning to attend, the country you applied from, the specific reason for the refusal, and whether you chose to reapply and what the outcome was if you did. Any insights, advice, or general tips about the application process or dealing with a refusal would be greatly appreciated as well. Thank you so much in advance for your help!
