Hi I dont live in Qld so no help there...
The morphology scan is the 18-20 week scan, I think it is the one pretty much everyone has as they check for growth and all major organs and body parts etc - so you have a good indication of the overall health of your little one. In my experience it takes a little longer than the other scans as they are v thorough in the checking.. I loved it tho as you see every detail. It is also when you can usually findout gender if you want to...
