Aussie here: Good riddance. This country is at the end of Earth in terms of supply chains and export markets, has a small local market and has extremely high labor costs -- all in all, a terrible place to build the kind of megafactory you need to stay competitive these days. The only reason they managed to survive even this long is massive government subsidies, and I applaud the fact that the government had the guts to finally pull the plug.
All that said, the transition away is going to have a high human cost, particularly in Adelaide which just doesn't have a whole lot else going economically. But my wife used to work for a Ford supplier in Melbourne, and that city has managed to absorb Ford's shutdown a few years ago without too much pain. (Nearby Geelong, though, had both the main factory and a steel mill, and is having a harder time.)
