There are a lot of riders use the car busy Doncaster Rd to get to Centennial and then head to the city and Redfern from the Pagewood area of Sydney. I tend to use this cycle route that follows near Southern Cross Drive starting at the pedestrian tunnel under Gardiners Rd.
You can see the trail on our Sydney map here just west of Southern Cross Drive >>>
