Australian National University Essay?

Hi, I’m planning to apply to Australian National University as an international undergraduate student (Engineering or IT). I was wondering if there is any required personal statements/essays (like US universities) for the application? I created a dummy account and didn’t find the column or space for essay, but I found some websites that said personal statements are needed for ANU.

So is there any personal statements, mandatory or optional? And if yes, where is it in the application?

Thanks a lot!
