I'm using QGIS to map weed locations and have a mixture of data from GPS, shapefiles of contours, OSM all in a project with CRS WGS84 (lat, long). I am trying to add in a shapefile I have been given which is in GDA eastings and northings but can't get it to mix with the other layers.
Lat for this area is ~-35, long about 149. Can't find an existing CRS definition that works - can get the right lat but the wrong long (~119). What do I do?
Hope this question makes sense as I'm pretty new to this GIS stuff.
