I do understand the high BA charges usually correlate with expensive property purchases. I don't want to spend more than 250k so realise charges for me should be cheaper. Not sure I'll find the IP I'm looking for in Aus but will keep exploring.
You will find it very difficult to find something for 250k in Melbourne's outter suburbs without including BA fees.
I did a search and 3 Brm place in Wallan (regional Victoria) is advertised 280-300k http://www.realestate.com.au/property-house-vic-wallan-117316003
Even a townhouse in Dandenong for 2brm is $230,000+ http://www.realestate.com.au/property-unit-vic-dandenong-117379915
The BA may still charge the same as another property in commission as they are going to have to drive 1hour plus each way to inspect a property.
