BankWest self insure with QBE and Suncorp insurer with QBE, so you have the same insurer behind both of these lenders.
I did a 97% not long ago with Suncorp, single income client but very strong income and great credit history.
Exit fees from liberty:
Rebatable Establishment Fee 3% of the original loan amount which is due upon early repayment. (AAA -Clear - Credit level fee = 1%) The fee is waived after 4 years
