Collaroy is part of the Northern Beaches region, about 22km north-east of Sydney’s CBD, in the local government area of Warringah Council.
Collaroy’s surf beach joins Narrabeen Beach at Wetherill Street, making one continuous 3.4km surf beach. Four Surf Lifesaving Clubs provide supervision and rescue services (North Narrabeen SLC, Narrabeen SLC, South Narrabeen SLC, and Collaroy SLC).
Collaroy's shopping precinct is along Pittwater Road, which runs north-south through the suburb. Small retail businesses include butchers, fruit shops, restaurants, furniture and renovation shopfronts, automotive services and home services. Other facilities and businesses include a cinema, RSL club and hotel.
Public transport comprises buses operated by Sydney Buses, south through to the CBD and Manly, and north to the suburbs from Narrabeen to Palm Beach. Driving to the CBD takes about 35 minutes outside peak periods and 60 minutes during peak. There are no train services.
Collaroy beach is one of the most highly developed shorelines in the Warringah local government area, featuring houses and apartments built in dune zones, with no roads or footpaths between them and the beach. Council regulations no longer permit construction so close to the beach.
The suburb is serviced by several public and private schools and hospitals.
Collaroy is home to one of the Salvation Army's largest conference and outdoor education centres in the area. The centre caters for Salvation Army conferences as well as other churches, schools, community groups and businesses.
