Australian Senate Committee Member Says Australian Fiber Optic Connections Are One of the Most Expensive in the World
According to an Australian network report, an industry expert stated at the Senate Committee meeting that as the National Broadband Network (NBN) does not use cheaper new technologies, Australia has become one of the most expensive countries in the world for fiber-to-the-home (FTTP) network connectivity.
According to reports, Tucker, a telecommunications expert and professor at the University of Melbourne, said that the average price of Australian FTTP connections is AU$4,405 per user, but the average price between New Zealand and the United States is only AU$2677 and AUD2259.
Tucker said, "Even if it is not yet the world's most expensive, Australia's FTTP promotion costs will become the highest in the world." He believes that Australia's FTTP connection costs are so high because not using the latest technology.
It is understood that in the United States, Verison, the telecommunications operator, halved costs at the beginning of the promotion of fiber optic networks in France and Spain, and the operator Orange reduced costs by 10% annually. In contrast, "the Australian national broadband network claims that the cost is fixed."
Tucker pointed out that due to lower costs and "no more stringent construction standards," many developing countries have lower FTTP connectivity costs than Australia.
"The data shows that many countries with high gross domestic product per capita like Australia have significantly lower costs for deploying FTTP networks than Australia," said Tucker.
However, the national broadband network did not respond to Tucker's accusations. A spokesman for the National Broadband Network stated that “the high cost of deploying FTTP links at each home is the reason why almost all countries use hybrid technology to achieve higher speeds. From small countries such as Singapore that cannot implement FTTP networks to the United States and Big countries like Canada are using hybrid technology, just as we do."
It is understood that at the launch ceremony of Australia’s national broadband network, the former Labour government had promised that no matter how much overhead, it will achieve a FTTP link with 93% coverage, and the rest will be covered by the satellite network.
