We have been working with various government organisations in the UK on publishing and consuming linked data and I’d be happy to share some experiences of how that went (though haven’t worked with any Australian organisations).
It does indeed take more effort in data preparation than simply publishing a CSV or Excel file, but is aimed at a different set of use cases, more focused on data integration and API access to data to support visualisation or analysis.
