Seems like there's (or was) a bad receptionist spoiling this otherwise flawless centre. The receptionist I spoke to in phone and over the counter was polite, and the doctor called my name less than 2 minutes after sitting. Not bad for a appointment-less system!
Seating area is 5-star, spacey, tasteful and comfortable armchairs, not hard plastic seats lined up against the walls.
Long trading hours, no appointments necessary, pathology station inside building and bulk billing available - would recommend if nearby.
