This cache has been placed to mark the route of the National Broadband Network cable that was laid from Alice Springs to Darwin in 2010, closely following the alignment of the Old Stuart Highway through Alice, then switching to the Alice to Darwin railway line further north of town.
The NBN was switched on to a number of government departments in Alice Springs in late 2012. It is anticipated that households in Alice Springs will have the NBN connected in mid-2014.
Cache is a small plastic tube containing a pen and a log. There's a few swaps included as well.
