This is an old post, but I know people search these forums for Doctor names to get feedback (I certainly did!). So I am adding this here for people who search and find this thread:
We used Dr Jenny Ng in Melbourne Plaza for our checkup/scans. She charged us $600 each visit, of which we paid $120 and our insurance covered the rest. She is with Quality Healthcare so there was no forms or claims for us, the clinic arranges it directly with the insurer which was nice,
The visits included an ultrasound each time, as well as urine & mother blood tests on different occasions. We also had the OSCAR test after 12 weeks. We have had four visits so far, and waited 5-10 minutes every time which was fine. Her manner is reasonable, no nonsense but answered every question we had to our satisfaction.
The only bad point for us is we asked her to book Matilda for us, which she did on time (9 weeks!) but Matilda simply refused the booking. I guess they give preference to their favourite obgyns, however I was surprised we didn't even get on to a waiting list booking as early as nine weeks. This isn't a reflection on Dr Ng, just something to consider if you want to give birth at Matilda. In the end, we decided we were happier to continue with Dr Ng and we booked the HK Sanatorium instead.
