John Tongue is right. They are two quite different birds, one
established in and around Perth, WA (Laughing Dove), and the
other that is infiltrating locations in south-eastern Australia
(Barbary Dove or African Collared Dove). I've become quite
familiar with both, the latter in the northern suburbs of
Adelaide. And their calls are quite different, so there
shouldn't really be any confusion there.
I did some research into doves with collars a while back when I
wanted to identify a bird that showed up in my mother's yard.
There seems to be a lot of confusion about these birds, partly
because they have multiple names and partly because Barbary
Doves are probably not really a good separate species.
Barbary Doves are known as Streptopelia risoria. They're also
called Ringed Turtle-Doves or Ringed Doves. They're generally
regarded as a domestic form of the Streptopelia senegalensis,
which is commonly called African Collared-Dove, Laughing
Turtle-Dove or Laughing Dove depending on who is doing the
calling. Typically, Barbary Doves look like a much paler version
of the African Collared-Dove/Laughing Dove. In some places,
Barbary Doves are reputed to look more like a paler version of
Eurasian Collared-Doves, and there may or may not be some
hybridization going on where they meet. (I can't tell from the
information in Pizzey & Knight whether the Barbary Doves
established in Australia are a form with more Eurasian
Collared-Dove genes in them. If they are, that complicates the
issue.) Eurasian Collared-Doves are Streptopeleia decaocto. The
appearance of all three can be similar if you're not familiar
with them. I've seen numerous Eurasian Collared-Doves but only
one Barbary/African Collared-Dove. (The one that I saw looked
like the wild version, but given that it was visiting my
mother's back yard in the eastern US, I think it is safe to say
that it actually was a domestic escapee.) The differences become
more obvious if you're familiar with at least one of
them. There's some simple information about separating Eurasian
Collared-Doves from Barbary Doves here
<http://www.birdsource.org/Features/EUCDOV/>.
Eurasian Collared-Doves sound very different from typical
Barbary Doves. Sound is generally considered the easier way to
tell them apart if there's a chance of both being there. If
you're dealing with Barbary Doves that have Eurasian
Collared-Dove ancestors, I'm not sure what sounds they'd make
though. I would expect that enough Eurasian-collared Dove
ancestry could result in Barbary Doves that sound more like
Eurasian Collared-Doves as well as well as looking more like
them.
In any case, there's a recording of a Barbary Dove here

and a video with sound of two of them here

several clips of Eurasian Collared-Doves here
