In Australia as well they are advisory so are therefore not speed
limits. You can not be fined for exceeding the advisory signs.
The speed limit, and therefore maxspeed, is sign posted with a sign like
this:

So therefore using maxspeed for this is incorrect. The wiki states that
maxspeed is the "maximum legal speed"
http://wiki.openstreetmap.org/wiki/Key:maxspeed
For example, close by where I live is section of road that has a speed
limit of 100kph. Several of the corners on it are signposted with
advisory signs, one as low as 60kph. In my car I can travel all of this
road at 100kph without having to slow for the corners. However if I'm in
my 4x4 I have to slow for the signposted corners as it can not be driven
and at 100kph around them even though it is legal to do so.
I'd suggest using something like:
maxspeed=80
maxspeed:advisory=50 etc.
For the urban/rural default limits, in Australia for residential areas
unless signposted it's 50kph.
May areas had been changed by John_Smith with the following:
maxspeed=50
source:maxspeed=default residential limit in Australia
Not sure of the exact wording for the source:maxspeed but it's the
general idea.

How do you tag speed limits on curves and highway on/off ramps? At
least in Ontario, these speed limits are advisory only and signed with
a yellow sign (and sometimes on curves you will see a curve speed
limit sign and a higher general speed limit sign right beside each
other). I have used ramp_speed and curve_speed for this and taginfo
suggests that maxspeed:advised, maxspeed:advisory, recommended_speed
might be ways to tag this. See
http://www.mapillary.com/map/im/nGxJnKpP2dootXNmp2eV_g for a typical
example of a ramp speed limit in Ottawa, Ontario (this one is 60km/h).
Also how do you tag maxspeed which is unsigned? In Ontario the default
speed limit is 50km/h in urban areas and 80km/h in rural areas when
not signed. However, there have been proposals to lower the lower
speed limit from 50km/h to 40km/h. I have been using maxspeed=national
for this, is there a better way to tag this?
