The entire idea of invasive species is kind of fraught, because organisms migrate over time. Barren volcanic islands will become seeded with life. Past extinction events change the ecological dynamic. Technically, ocean life invaded the land hundreds of millions of years ago. Land bridges open up, continents collide or separate, etc. Humans weren't the only organism to migrate out of one continent onto others.

No. Invasive species are relatively new to the land, they disturbe the existing equilibrium often without any natural predators to hunt them and they wreak havoc. Like wild boars in USA. Like rabbits in Australia. Like humans on earth. Barren islands evolved for tens of millions of years in isolation were all over the world until humans built ships.
