The beautiful new Hospital for Specialist Surgery is now open for business. We are in Suite 4, which is on level one of the hospital, while the day surgery (and importantly) the cafe, are on the ground floor.



 consult roomThe hospital is in an amazing location with a beautiful lake and fountain next door, full of ducks, catfish and occasionally model sailing boats. You can look out over the lake from the cafe and consulting rooms, or go for a walk after your appointment.



Endoscopy and Colonoscopy procedures will be performed in one of the two brand new day surgery theatres. All the equipment is state of the art including High definition (HD) Olympus 190 series scopes, widescreen LCD screens and ERBE diathermy/APC. We will have the ability to remove any size polyp, perform complex EMR and dilations and investigate any gastrointestinal complaint. All health funds are supported and we continue to NoGap bill all procedures.


Consulting will now be every day of the week meaning convenience for patients and an ability to fit in urgent appointments at any time.

Appointment times are as follows:

Mon: All day (DVDP)

IMG 0805Tuesday: PM (DVDP)

Wednesday: PM (RV)

Thursday: AM (DVDP and WS)

Friday: AM (RV)


Although the parking is much better than at Westmead (2 hours free parking in the hospital carpark), make sure you know which way to enter the Norwest business park at certain times of day. In the morning peak never ever turn right off Old Windsor Road into Norwest Boulevarde. Take the 1st or 3rd entrances and work your way back. From the castle hill end (Windsor Rd) a direct turn into Norwest Boulevarde is fine.
