Thanks Martin, I ended up using the Georeferencer and the ground control point coordinates with a Helmert transformation. That worked well.

If it just a bit off, then the plugin "Freehand raster georeferencer" can be quick to shift it, otherwise use georeferencer from core (Layer - georeferencer), which is especially more flexible and the right tool if you have GCPs that you can use. Be careful, sometimes crashes can occur with certain transformation types, so better save beforehand (autoSaver and MemoryLayerSaver are your friends). > Image created in WGS84 z51S. Sound like UTM (good, metric CRS), though WGS84 might be geographic CRS (worse, pixel size undefined/different in x,y).
