551 is a route that plys between Eastwood to Marsfield. It only operates 2 services on weekdays AM peak Eastwood bound, and another 2 on weekdays PM peak Marsfield bound.

551 was renumbered from 549 on 27 August 2007.[1] This is likely due to the reorganisation of the former Harris Park Transport routes in November 2007 which resulted in the creation of 549 from Epping to Parramatta via North Rocks Road.
