If someone operating a web scraping service or was selling software might be willing to offer you $100 to $300 for it.
The problem would be that most web scaping services/software are offered by international providers so an AU domain isn't the ideal option and I think it would be hard to find an Australian business that would want it.
So for me it's more effort than it's worth, but it might be OK to park it away in your portfolio.
Fair to say the vast majority of people don't know what scraping is... even if their website already does it behind the scenes, they probably still wouldn't have a clue.
Those that do know are internet marketers, who generally speaking are price conscious and web developers who build the scripts.
