Yellow Thornbill or Weebill

I took these photos at Jerrabomberra Wetlands ACT 2weeks ago and I am not sure if it is a yellow Thornbill or a Weebill. I apologise for the photos but they were a large crop. I also have to say that I am not 100% sure it is the same bird as there were a few and they were flying around quite a bit.
