Want to study in uk but not meeting academic requirements

I want to do mba or msc from Australian university as i want to settle there and if not got pr atleast i will have good degree which will be helpful for my career but i did bachelor in Political Science and even after lot of research not able to find any university that will accept me

They all require bachelor degree in relevant field ( in commerce / business) but i did bachelor in Political Science ( as studying abroad was never my plan i always wanted to be a bureaucract)

Also i didn't done ilets tests but got 86 percentage in class 12th cbse board exams in english
