I didn’t say there was anything wrong with that.
There’d only be something wrong with that if:
1. it is not true that the majority of Australians can position to only 5 metres accuracy with current technology; or
2. it is true, but either:
a. the majority of Australians don’t need 3 to 5 centimetre accuracy; or
b. the benefits of achieving that accuracy do not outweigh the costs of achieving it.
