It's a long-running debate whether Sensis or HERE/Navteq is more reliable/accurate/up-to-date. It's not a winnable argument because it depends on where you look. [1] After at least annual reports, my semi-rural road is finally in the Sensis maps after being missing for many years while present on Navteq, but still as far as Sensis is aware there are only 3 house numbers, and only one of those is in the block where i'm located [not mine, it's the opposite neighbour though], but HERE has had all the house numbers for as many years as it's shown the road. It's not a new road, been around for 50-odd years. [2] A relative moved into a new rural-residential subdivision some kilometers away nearly a year back. Sensis still doesn't know about it [the entire subdivision], but HERE does and has done for the last few versions. I could find opposing examples around here as well bagging HERE like for Adelaide as quoted by you 2 [apparent] Crow Eaters. My point is that Sensis has ignored endless notifications and sometimes HERE does too.

My sincere advice, report the deficiencies where it counts, to HERE or Sensis as they might listen especially if its a built-up area or major arterial. Don't only comment here, and assume they'll find out themselves or that someone else will do it, just do it yourself as it takes but minutes. Remember 'The Stone in the Road' story? Or maybe you're too young to have had that in your Grade IV reader at school. Google it then, it's got a good moral [but sometimes responsibility, like goodness, can be it's own reward].
