Common mistakes with Australia MGA Zone 55 (GDA2020)
- Easting and northing swapped. In Australia MGA Zone 55 (GDA2020) the middle of the grid is near easting 500,481.95 and northing 6,674,566.12. If your easting column holds numbers like 6,674,566.12, the columns are the wrong way round and every point lands far away: swap them before converting.
- Feet entered as metres. Australia MGA Zone 55 (GDA2020) is in metres. Coordinates copied from a drawing in feet must be converted first, or every point moves outwards from the grid's origin.
- Forgetting the datum. Australia MGA Zone 55 (GDA2020) is not on WGS 84: treated as WGS 84, no shift (the datums agree to about a metre or better). Picking a WGS 84 grid with the same projection instead leaves the points off by that amount.
- Points outside the grid's area. Australia MGA Zone 55 (GDA2020) is meant for Australia - onshore and offshore between 144°E and 150°E. Points well outside that area convert with growing error; the converter flags them so you can choose the right grid.
- A local site grid. If every point is off by the same distance and direction, the drawing may be on a local site grid. Calibrate on three or more known control points instead.
Before you rely on it
Older data is often on GDA94 (EPSG 28355); it differs from GDA2020 by about 1.8 m. Always check one known control point before sending a file out.
