Gondwanan pre-Cretaceous ceratosaurs?  Yes.  Elaphrosaurus and Ceratosaurus
from the Tendauguru at least.
If you meant Australian Cretaceous ceratosaurs, I blame my confusing
writing.  The groups I listed are not ALL seen in Cretaceous Australia
(lacking provable ceratosaurs and basal coelurosaurs), but we do see a large
diversity of taxa.

Let us not forget we're discussing Gondwana.  North America and Europe were
separated from Gondwana by that time.
