Totally normal for Aussies. They are bred to be very attached to their humans, so following you around is just part of their nature. My dog will even sit outside the bathroom door if I leave. It's sweet but sometimes a bit much!

My Australian Shepherd does the same. They thrive on companionship and want to be where the action is. It's like they have an invisible string connecting them to us.

Definitely seems like a Velcro dog to me!
