OK, brain not working. I mean you need to be in the right lane to go 
straight through.

Andrew, are you familiar with this intersection from travelling through it?



No, and it may be some time before I could visit in person :-(

I came across this one because it had a broken turn restriction. Based 
on what had been mapped I assumed that someone was trying to give lane 
guidance. This is just a standard roundabout except for the fact that 
you need to be in the left lane to turn left on some of the arms.


OSRM and Graphhopper will give you correct directions (ie take the nth 
exit on the roundabout) but OSMAnd fails to notice you are going to 
drive through a roundabout. The first two routers are getting the 
correct answer by accident because the fake slip roads have been tagged 
as _link, as a result the router prefer to follow the main road into the 
roundabout.


It had occurred to me that the same outcome (lane guidance) could now be 
given using turn and change tagging.

Re: [talk-au] In-water fences?

[Warin]

There are fences for long distances in/on (depending on water level) 
Lake George (near Canberra).


There are also fences across water ways.

They are all stock control so barrier=fence is the correct tag there.

Just chose the most appropriate tag.

The "snag hotel" is better known as a fish crib. The second thing
is a
revetment.


There is a seamark:obstruction:category=crib with a grand total of 7
uses and man_made=revetment with 37.
