nbn Fixed Wireless towers boast new bird’s eye views
4-minute read
Australians are very attached to their nbn connections, but none more so than the feathered friends that have taken up residence on our Fixed Wireless towers.
With breathtaking views, no neighbours and a cosy open plan, it’s no wonder that nbn’s Fixed Wireless towers are prized real estate for some of Australia’s most discerning homemakers.
Standing 30 to 90 metres high, nbn Fixed Wireless transmission towers connect some regional, rural and remote Australian areas to the nbn® network by transmitting data via radio signals.
Of the almost 2,400 steel structures dotted around the country, more than 500 are home to nests built by Eastern Ospreys, White-bellied Sea-Eagles, Peregrine Falcons, Torresian Crows and other native birds.
Thirty of these nests are significant, with diameters of up to two metres and weighing anywhere from 60 to 100 kilograms.
As impressive as these lofty lodgings may be, nests often obstruct access to antennas and dishes, making it impossible for nbn technicians to repair, replace and upgrade equipment to keep customers connected without disturbing the birds during breeding season.
Elevation innovation
To keep both the birds and broadband lovers happy, nbn has come up with an innovative solution.
We’re upgrading the roosting residents to penthouse suites, installing nesting platform extensions on top of existing towers, above the active equipment. These platforms provide a safe place for native birds to nest, lay, hatch and fledge, away from the critical infrastructure we need to access to maintain our network.
During the upgrade, existing nests are carefully bound with straps, lifted intact off the towers with a crane, then replaced on the nesting platforms.
The first platform was successfully installed in December 2023 and, this year, the first relocated nests were used to nurture a new generation of chicks.
New nest neighbourhoods
So far, seven nesting platforms have been installed on Fixed Wireless towers in Darawank, Hat Head, Old Bar and Salt Ash in New South Wales (NSW), and Boreen Point and Campwin Beach in Queensland (QLD).
Eight additional platforms are due to be installed in Minnie Water and Wooli in NSW, and Beachmere West, Cowley, Maaroom, Meldale, Mowbray and Toorbul in QLD.
Casie Scott, Regional Development and Engagement Manager at nbn, is thrilled the specially designed nesting platforms were used by returning native species this year.
“Protecting natural environments has always been a core responsibility of nbn, as the construction, operation and maintenance of Australia’s largest infrastructure project carries the potential for adverse impact.
“This work is a perfect example of how we can minimise impacts on native flora and fauna while delivering reliable high-speed connection to regional, rural and remote communities.”
Working on the project since its inception, Sam Turbill from SMT Ecologists believes it’s a great news story.
“This is the best possible outcome, both for the species and for the communities that rely on Fixed Wireless as a critical service.
“Given the loss of large, dead nesting trees on the east coast, these artificial nesting platforms are a great solution for providing stable long-term nest sites for species like the Osprey, while allowing for the required maintenance of infrastructure on the tower to be completed without disturbance to the species.”
Meet the Flockers
Peregrine Falcons
The fastest animal on the planet, Peregrine Falcons reach speeds of 322 kilometres per hour (kph) when in a hunting dive and horizontal cruising speeds of up to 90kph. Their nostrils guide shock waves of air to stop the high pressure from damaging their lungs. They inspired the first jet engine design.
Torresian Crows
Intelligent and adaptable, Torresian Crows are known to steal food from larger birds by working in teams, and attack larger birds of prey, particularly wedge-tailed eagles and most owl species, to defend their nest or territory. Large groups of all ages congregate and roam nomadically across farmlands, forests and city suburbs from January to August.
Eastern Ospreys
Known as excellent anglers, Eastern Ospreys' fishing success rate is as high as 70 per cent. They fold their wings and dive feet forward, often completely entering the water where they can see thanks to a unique third eyelid called a ‘nictitating membrane’, which works like a pair of goggles.
White-bellied Sea-Eagles
Found across Southern China, South and Southeast Asia, New Guinea and Australia, White-bellied Sea-Eagles mate for life and can continuously occupy nests for more than 50 years. Juveniles are dispersive, and one raised in Cowell, South Australia was identified 3,000 kilometres away on K’gari (Fraser Island), Queensland.
What is Fixed Wireless?
Fixed Wireless is used to connect some regional, rural and remote Australian areas to the nbn network, where fixed line technologies aren’t typically available.
A Fixed Wireless connection is created by transmitting data via radio signals from an nbn Fixed Wireless transmission tower. These transmission towers are built in chains connected to each other through microwave links, with the hub transmission tower connected directly to an exchange via fibre.
The customer’s premises receives the signal via an nbn external antenna. This then feeds the signal via a connecting cable to an nbn connection box through a wall outlet inside the premises.
