Warriewood is a suburb North of Sydney and under the government of the Pittwater Council. The history of its name stems from the estate – Warriewood Estate from where the land was a part of. The land between Warriewood Valley and Mullet creek was granted to James Jenkins and he had established the Cabbage Tree Hill farm here in 1829. The Macpherson family have the credit of naming the land Warriewood. But only much later did Henry F. Halloran subdivide the land in 1906 to form the different suburbs after purchasing it from the McPherson family

Warriewood remains largely undeveloped although there are plans underway since 1997. The original plans com under the Warriewood Valley Urban Land Release Planning Framework 1997 as well as the Draft STP Buffer Sector Planning Framework 2001. However the plans were reviewed just recently in the Warriewood Valley Planning Framework 2010 which will see over 2 thousand homes being built.
Further land area was identified in 2011 and 2012 for more development in Warriewood Valley and the Southern Buffer. The plans are drawn out under the Warriewood Valley Strategic Review Report 2012.
