Holden Astra!
It's ok as a name. Different and yet easy to pronounce. It sounds kind of happy to me.
Though the
Astra car is quite common at the moment in Australia so that makes it a little hard to use. But generally once people know someone with the name they tend to ossociate them with the name over other things.
