Does anyone know what average TEA scale or approximate % out of 100 each subject to get Atleast an ATAR 80+?

I’m a June express intake just finished his Semester 2, going into Semester 3 I have around 70% English, 61% Economics, 64% Maths Methods, 67% physics and 65% BME. I’m concerned if with this marks I can get Atleast an ATAR 80. Does anyone have reference to what ATAR they’ve gotten to get Atleast in the ATAR 80-85 range.
