I'd say Curtin is unlikely as well. From what I hear, someone in my school DIDN'T manage to get a Curtin interview offer with a 99.8 predicted and a 90th percentile UCAT, and the common concensus is that it is much easier to get a UWA interview than it is a Curtin one. Note that UWA interviews seem very easy for local WA applicants to get but not for interstates, whereas Curtin has very high cutoffs because it is thought that they have the same cutoffs for interstate and local applicants. What I'm trying to say is this: UWA's interview cutoffs, whatever they were for local applicants, can only go up. Curtin's is most likely to stay the same at the high point that it was set at for the local applicants. However, I don't think interviews at Curtin or UWA's second round has come out yet, so it is possible that cutoffs drop and interviews are sent out.
What do you mean that UWA and Monash don't interview? They do have interviews. If you meant that they strongly favour local applicants and have very few interview slots for interstates then that is correct - but they do interview nonetheless.
