Ospreys and our shared coastline

Residents of Mission Beach may recently have seen reports about upgrades to Telstra communication towers being delayed after nesting ospreys were discovered on the structures. The decision to postpone works until the chicks have hatched and fledged is an excellent example of practical coexistence between people and wildlife – and a reminder of how important human infrastructure has become for some coastal raptors.
The Eastern Osprey (Pandion haliaetus cristatus) is one of Australia’s most recognisable birds of prey. Specialised fish hunters, ospreys are superbly adapted to life along coasts, estuaries and large waterways. Their reversible outer toes, heavily spined feet and long curved talons allow them to grip slippery fish with remarkable efficiency, while their dense, oily plumage enables them to plunge feet-first into the water and emerge airborne with prey.
Unlike many raptors, ospreys build very large, conspicuous stick nests that are often reused and added to year after year. Traditionally these nests were built in tall emergent trees – particularly dead trees with open visibility over waterways – but across much of Australia suitable nesting sites have declined through coastal development, vegetation clearing, cyclones and fire. As a result, ospreys have increasingly adapted to artificial structures including navigation markers, channel beacons, cranes, light towers, power poles and telecommunications infrastructure.
Mission Beach now appears to support at least three nesting territories associated with communication towers, with local observers reporting strong breeding success in recent years. This reflects the species’ remarkable adaptability, but it also highlights an important conservation reality: in many developed coastal landscapes, artificial structures are effectively replacing the ecological role once provided by large old trees.
The use of human infrastructure by ospreys is not unique to Far North Queensland. One of the best-known examples in Australia occurs at Polytec Stadium on the NSW Central Coast, where a dedicated nesting platform was constructed atop the stadium lighting towers for a resident osprey pair. The birds became local celebrities, attracting widespread community interest and demonstrating how purpose-built infrastructure can successfully support breeding raptors while allowing human activities to continue.
Here in Mission Beach, local bird enthusiasts are now working with Cassowary Coast Regional Council, tower owners, the BirdLife Australia Raptor Group and the Port Lincoln Osprey project to investigate the installation of a live webcam on one of the nesting towers. Similar nest cameras elsewhere in Australia have proven enormously popular, helping to build public awareness and appreciation for raptors while also providing valuable behavioural and breeding data. Support for a Mission Beach osprey webcam could create a unique community and ecotourism asset while further strengthening the connection between local residents and their coastal wildlife.
Although Eastern Ospreys are not currently listed as threatened nationally, they remain vulnerable to disturbance during breeding. Eggs and chicks can overheat or become exposed to predators if adults are repeatedly flushed from nests. Nesting success can also be affected by severe weather events, marine pollution, entanglement, declining water quality and reductions in local fish abundance.
As highly visible apex fish predators, ospreys are also important indicators of coastal ecosystem health. Healthy osprey populations generally reflect healthy fish populations and functioning estuarine and marine food webs. Their continued presence in places like Mission Beach is therefore about more than the survival of a single charismatic species – it speaks to the broader ecological condition of the coastline itself.
The recent decision to delay tower works until the nesting season is complete deserves recognition. In a rapidly developing coastal environment, small acts of accommodation like this help demonstrate that infrastructure and wildlife do not always need to exist in conflict. Sometimes, with a little patience and planning, there is room for both.
The discussion around Mission Beach’s nesting ospreys was prompted by the article “The beauty of nature” by Nick Dalton, published in The Observer – Cassowary Coast on 13 May 2026. We thank local observers and community members helping to raise awareness of these remarkable birds and their coexistence with coastal infrastructure.
