We're missing the really big invasion into Australia -- sheep!  
They eat away shrub and farmers clear away bushland for them to graze.
The kangaroos love this and consequently there are more now than before
European settlement.  Many other species, especially koalas, suffer as 
the native bush is pushed back.

I'm not sure if the crown of thorns starfish was a native or an invader
but some years ago it was a plague upon the Barrier Reef.
