I highly doubt that. Only like 100 people in the sate get that or above, and less than 50% want to do med...
And surely not all of those 100 would have gotten 190 combined score, or even done the UMAT... well I sure hope not!
If they're having 200 interviews then it would have to be lower... hopefully... 
I don't think JDog meant 99.8+ as an ATAR floor. That's with a UMAT percentile of 92; suppose your UMAT percentile is 95 and 96 was the cut (hypothetically) you might only need a 99 - again they simply take people who don't already have an interview, get their ATARs and UMATs, mash them together to get a combined total, then take the top ~200.
Having said that 99.8+ with a 92nd percentile UMAT I think is a tad high - I'd think closer to 99.6 (remember this is for interviews, NOT admission).
This information may help; of the CSP metro students in first year med this year (excluding bonded):
ATAR (median) = 99.30
UMAT (median) = 62 (I think this was 95th percentile last year)
Interview (median) = 86 (presumably out of 100)
