Can't seem to find a way to implement GDA94>GDA2020 OTF Transformation.
QGIS has support for GDA2020 now.
There are 3 options in EPSG now for this transformation and PROJ seems to support the methods, but i can't find a way to use them in QGIS.
The three EPSG codes for transformation for onshore Australia are:
8048 (Helmert Transformation)
8446 (Conformal Grid Transformation with associated GSB)
8447 (Conformal + Distrortion Grid transformation with associated GSB)

I should also have said that i have tried to choose the default transformation through the options dialogue, but when selecting 4283 and 7844 there are no options shown in the source and destinations transformation box.
I have also installed the GSB files using the OSGEO4W download tool choosing the proj-datumgrid-oceania option in the setup tool
