Yes just got the rejection letter only, not banned, I guess this could because I was a minor (15 yrs old) when I got the Australian visa rejection and last year I just turned 18 and applied for the visa. This time my application documents are more strong than previous time as I provided every necessary document. Honest mistake as in a sense that I was not aware of the rejection as my parents did the Australian application when I was a minor and as I visited Australian on 2016 I wasn’t aware that I had the rejection. And I assumed i had no rejection. I should have been more careful while making the application. This is how I explained it more briefly.
