Hi Robert,

I think you hit some kind of wfs-data issue here.

If I open the url in a browser:
http://openapi.aurin.org.au/public/wfs?SERVICE=WFS&REQUEST=GetCapabilities&VERSION=1.1.0

Or time it using curl:

time curl
"http://openapi.aurin.org.au/public/wfs?SERVICE=WFS&REQUEST=GetCapabilities&VERSION=1.1.0"

real	0m20.490s
user	0m0.090s
sys	0m0.716s

You see it is not a fast service, but seemingly ok.

What I do see is that the 'Abstracts' of the layers are very strange
formatted, looking like it is instead of a string some serialized java
(see below).

Mmm, requesting the service again, I see the file is just HUGE (56Mb)
and containing what looks like escaped html from some australian census
website...

So I think somebody has to fix that service first...
(I was creating an issue for it because QGIS should not fail on
capabilities I though, but this output is toooo strange (and 56Mb large)...

Regards,

Richard Duivenvoorde
