The complex and expensive national infrastructure project to create a National Broadband Network
in Australia is underway. Not surprisingly it is taking longer and costing more than initially hoped and now the opposition is proposing to cut costs by cutting an important corner.
Rather than doing the hard part, taking optical fibre to each home, they propose to run fibre to nodes and re-use existing copper to get to houses. This approach will deliver an improved internet at a lower cost but both only in the short term.
To me, it's like building a highway system with dirt road off-ramps.
Looking back at the history of internet speeds it's clear that speeds grow logarithmically and there is not sign that this will slow or stop. It's inevitable that the last mile of copper will be a choke point and a future government will have to come back and finish the job.
ABC Radio National Breakfast aired interviews with me
and finance correspondent Sheryle Bagwell
where we looked, in turn, at the technical and financial analysis of the alternate plans.
As I said in the interview, this is not really about politics, it's about the relentless march of technology.
