Thanks Sue and Birdboy, I'm still not sure but I managed to get some more shots of the bird today in better light and closer. It still doesn't look like the Lemon Bellied in my reference. In these shots you can see a definite buff chest, yellow rump and olive-yellow wings. Size wise, the first sight of this guy it would be easy to mistake for an Eastern Yellow Robin. If someone could point me to a definite ID comparison picture somewhere it would be appreciated.
One thing that disturbs me regarding calling this a LB Flyrobin/flycatcher is that the strongest yellow is on the undertail coverts on this bird, while the yellow is relatively weak on undertail coverts in the photos of LBF in the gallery. Especially the Queensland female of Golden Whistler would be expected to have those strongly yellow undertail coverts. I am not sure that the bird actually is a golden whistler, but I am not at all convinced it is a lemon-b F either.
cheers

The Golder whistler Sue linked to in post 8 is almost exactly the same as one of the images of the unknown bird (http://www.birdforum.net/attachment.php?attachmentid=137957&d=1209888876) except for the stronger yellow undertail coverts. My Pizzey & Knight shows such strong yellow undertail coverts on the female GW from QLD, while the drawing of a southern bird is close to the image Sue linked to. I think it is a Golden whistler, with Mangrove GW an outside possibility (if I remember correctly, rather difficult in QLD).
The yellow wash in the wing Chowchilla referred to may be a color cast from sunlight reflecting of leaves or the camera not getting it right in the images where it does occur; dont seem to be present in all of them.

Edit: I just noticed that the MG race, robusta would be the one found in Queensland and that race does not match Trevs bird. The female has a yellow belly and black tail (Morcombe).
Thanks guys for all your feedback and thoughts. I took this guys pics at the top of my driveway on the top end of the Gold Coast, Queensland. The property is bounded by the Albert River and has Mangroves all along it but this was taken up on the start of the ridge in the dry forest area. We do get Golden Whistler here but I haven't seen a male around or heard any calls. I'll head back into the patch if we get some sun this afternoon and see if she is still around.
This link looks fairly similar but perhaps mine is a juvenile female as the barring and eye markings don't seem as pronounced
