The Coastline Paradox.
Australia’s coastline is somewhere between 25,000 km in length and 60,000 km.
The distance depends on the method used to measure it.
The more precise the measuring device, the more accurately you can capture the bays and inlets and coastal indentations.
The degree of precision needed depends on whether you’re a mariner or a geography teacher.
There will always be one who has the motivation, patience, and time to make finer measurements than yours.
Remember that next time someone critiques your words or your work.
