Hi Judith,
I think that Philip's very good suggestions of mimicry by Olive-backed Oriole
and Satin Bowerbird could be considered as possibly the source of the Green
Catbird-like call that you heard.
And further, I have seen a few pretty good southern birders 'tripped-up' by a
Yellow (Green) Oriole's scolding call up here, thinking at first they had heard
a Spotted Catbird.And I know that O-b Orioles make a similar call to this.
And what about the possibilty of it being a Figbird that you heard? HANZAB is
inconclusive as to whether they do mimic, but I have heard them do so, and
they're pretty good at it too - they are orioles after all...
But of course, it could have been a catbird making the call. Up here in The Wet
Tropics there is some very local post-breeding dispersal undertaken by Spotted,
but I've only seen them in vine(rain)forest at this time. Perhaps others up
here can add comment to this.
Maybe down there Green Catbirds also disperse after breeding... Do you have any
good fruiting trees/orchards nearby to your place??
It's worth thinking about I reckon... Until at least you here the call again
and can track it down.
cheers for now,

Thanks, Philip, I reckon I can add this to my house list in good conscience
now! Still amazed.
Cheers
