Hi Alan and Birders
There were more than 75 Osprey nests in 2002 between Lake Macquarie and
the QLD border. In a comprehensive study undertaken by ECS in 2003,
there were at least 90 nests in all catchments between Lake Macquarie
and the Queensland border in 2002, with the exception of the Clarence
Catchment. In 2003, 118 nests occurred in that area. Of these 81
were in trees, 24 on dedicated nesting poles (erected by NPWS,
electricity, telecommunication authorities); 4 on active power poles; 3
on dedicated towers; 2 on a light pole and an active tower; a nest on a
span of a railway bridge, a nest on a pontoon (1m above water level) in
a lake, a nest on the ground, and a nest on a disused crane derrick.

Hi Birders,
In NSW in 2002 there were 75 pairs of nesting Ospreys between Lake
Macquarie and the Queensland border. About 14 pairs of which nested on
artificial structures constructed for that purpose, usually by NPWS or
the local electricity authorities.
The nesting of the Ospreys at Narrabeen Lagoon reported by Bruce Cox
is of interested because it is the first breeding record for the
Sydney Region, and the most furthest south in NSW. The most southern
nesting effort prior to this was at Kincumber meadows, Brisbane Water
on the Central Coast in 1995 but this attempt failed. The next most
southern pair is at Wood Point, Lake Macquarie where they have been
nesting now for a number of years. In the mid 1990s another pair
nested near the Eraring Power Sation on Lake Macquarie, but then there
was a gap for 4-5 years before the nesting at Wood Point commenced.
North from Lake Macquarie, there is a gap of about 100 km before
reaching Port Stephens where there are several nesting pairs.
Pairs are often reported from the South Coast and from the Northern
Tablelands but as yet no nests have been found.
