There has been a set of transformation grids released to help people convert their datasets.
GDAL/OGR should add support for these conversions.

The grids were released in proj-datumgrid https://github.com/OSGeo/proj-datumgrid/releases/tag/oceania-1.0. I presume that support will automatically happen when you have the latest proj-datumgrid installed on your system?

You will have to specify them in the proj.4 string to express the transformations.

This ticket has been automatically closed because Trac is no longer used for GDAL bug tracking, since the project has migrated to GitHub. If you believe this ticket is still valid, you may file it to https://github.com/OSGeo/gdal/issues if it is not already reported there.
More details have been published in the technical manual at http://www.icsm.gov.au/gda2020/GDA2020TechnicalManualV1.1.pdf
The transformation grids are now available at https://github.com/icsm-au/transformation_grids
