Accessing the spatial reference information of a few GDA2020 feature classes through specific methods shows an incorrect coordinate system, GDA94.

Workaround

The issue is not replicated when (workarounds):

1. Export it to a shapefile, or a new feature class.
2. Follow the documentation below and copy the feature layer or feature dataset to a new file geodatabase.
3. Follow the documentation below and copy the feature layer or feature dataset directly to the same file geodatabase.
