MGA Zones Map Australia
MGA zones are vertical 6-degree map strips in the MGA grid, the Map Grid of Australia.
This visual guide answers MGA map, MGA zone map, map grid Australia, and UTM zones Australia searches with city examples and longitude lookup.
A complete Easting and Northing coordinate only makes sense when the matching MGA zone is known.

Common questions
What is the Map Grid of Australia?
The Map Grid of Australia, or MGA grid, is Australia's metre-based projected map grid. It divides Australia into MGA zones so locations can be measured with Easting and Northing.
How do I find my MGA zone?
Use longitude or a city position. Sydney is in MGA Zone 56, Melbourne is in MGA Zone 55, Perth is in MGA Zone 50, and each zone is a 6-degree longitude strip.
Is MGA the same as UTM in Australia?
MGA follows the UTM zone pattern for Australia, but the datum matters. MGA94 uses GDA94 and MGA2020 uses GDA2020.
