And I find plenty of bitumen roads that don't appear on a sat nav using Sensis maps, along with plenty of tracks through private property that do appear but shouldn't. :) The Sensis maps (Whereis) can be very inaccurate outside of towns and cities. Misnamed roads and/or mispelt names are also common errors. Another problem is roads that don't start or end in towns or cities, which often have a unique "city" address in the Sensis maps. More often than not the residents won't even know their "Sensis" address. Garmin can usually find those roads (under "search all") without being told which "city" while TomTom can't, however I still wouldn't recommend either as the sole means of finding your way about in the bush... even when they do recognise the address you're headed for. -- John H
