It does look like Limnodynastes tasmaniensis, the Spotted Marsh Frog. Another possibility is Limnodynastes fletcheri; the Barking Marsh Frog; but I'm going with the former.

An eye injury that gets a bacterial infection can look cloudy and if advanced could also make eye bulge out beyond normal. Because of infection location, a visit to veterinary is recommended.

It does not matter what is a new frog source; it should always be quarantined before introduced to a vivarium or similar enclosure. Time and money invested in preparing a vivarium is enough reason to do that, even when there are no frogs in it. Good luck !
