Please explain what your idea of a good credit rating is. You're likely thinking of what they use in the US. Australia only had neutral to bad credit ratings (there's no such thing as 'good').
If you've bought a house or two in the last year and done one or two other things to trigger a credit enquiry, you may well find that your rating is actually 'bad' when it comes to a 95% lend, even though you never miss a repayment.
How easy it is to get a 95% loan will also depend on how leveraged you are with your other investments and how good your affordability is.
No debt only good mortgage debt
No credit card debt
mortgages paid on time everytime

Would a credit enquiry be triggered by me opening up a new bank account or similer?
