Bonnells Bay is a suburb of the City of Lake
Macquarie in New South Wales, Australia on a
peninsula east of the town of Morisset on the
western side of Lake Macquarie.

The town of Bonnells Bay, known as Morisset
East until 1948, is named after the Bonnell
family, particularly William F. Bonnell, the first
settlers of the majority of what is today Bonnells
Bay and parts of Windermere Park and Morisset
Park. The Bonnell family also have a bay which
is part of Lake Macquarie named after them,
Bonnells Bay. The Bonnell family owned what is
today all of Woods Point, now a national park
and parts of the northern grounds of Morisset
Hospital over north to the Lake Macquarie
foreshore of what is now Bonnells Bay. The
Bonnell family are not in relation to the early
settlers of Mandalong the James C. Bonnells.

The area was subdivided in 1886, but no
township was established until after World
War II. The Bonnells Bay township grew, and a
small shopping centre built, after the
development of the Eraring Power Station
in the 1980s. A school operated from 1912
onwards.

Bonnells Bay has grown considerably since
World War II, the school which opened in
1912, Bonnells Bay Public School has grown to
capacity, large proportions of the suburb are
increasingly being subdivided and the
shopping centre now consists of a newly
developed 'The Bay Shopping Centre' with a
Club, Coles, Post office and many convenience
stores.
