Run:
docker-compose run dataloader /bin/bash
./load.sh
If you have not already downloaded the census, it will be downloaded and extracted.
Once that has run successfully, consult the output and run pg_restore on ./tmp/aus_census_2011 into your actual EAlGIS database. Don't forget to run VACUUM ANALYZE; too.
pg_restore --username=postgres --dbname=postgres /app/aus_census_2011
