A suburb name is useful for beginning a search. It is rarely enough to judge a property.
Two homes in the same suburb can have materially different exposure to traffic, slope, bushland, drainage, aircraft noise, planning controls and walking access. Those differences affect daily use, future buyers and the price evidence that deserves the most weight.
My approach is to move from suburb to pocket, then street, then site. I compare the property with sales that share the characteristics buyers are likely to notice, rather than relying on the nearest transaction or a suburb-wide median.
The limit is that no map or dataset substitutes for inspecting the position. But checking the street before becoming attached to the house is usually a better order of operations.
