"One context I think about when the RBA uses its so called big stick to curb inflation is that it hits mostly the home buyers. ie. the ones with the mortgages. With increasing costs of homes, the increasing size of mortgages doesn't this mean a greater effect of each interest rate rise. Maybe a multipication factor etc."
The RBA are well aware of this and have recently said as much themselves. That doesn't mean they will stop raising rates if they need to.
