abroad student loan without collateral

i’m planning to move to australia for my bachelor’s degree and i’ve received offer letters from two universities. i applied for an education loan with sbi, but they’re not approving it because of an issue with collateral. apparently, due to a new rule, the loan amount they’re willing to give dropped from 85 lakhs to just 6 lakhs.

the deadline to pay my fees for the university i really want is april 15th, so i’m really stressed about figuring this out in time.

is there any way to get an education loan without collateral? how does that process work, and are there any banks or options i should look into?

any advice would really help right now.
