Can I enter Australia in January 2025 even if my course starts in March 2025?

My visa was granted May 2024, but my intake will start on March 2025. Is it okay to go to Australia by January 2025? Also, I already paid my OSHC extension.

I guess it’s okay to go to Australia 4-6 weeks prior to your course starts as it is understandable that you need to look for accommodation, transport and other arrangements. But going much before 6 weeks will be considered illegal, I suppose.
