Building Footprints Dataset - How to get it in?

Hi All

My Name’s Alex Leith, and we’ve released a reasonably complete dataset of building footprints, see here: https://data.gov.au/dataset/glenorchy-city-council-building-footprints or here: https://maps.gcc.tas.gov.au/metadata/buildings.html

I wonder what is the best way to get those data into OSM?

Regards,

Alex
