bright orange Red-capped Robin

A query from a birding friend. Anyone able to help please?

Steph and I returned from a trip into Queensland a very short while ago and I came back perplexed about a bird (two actually – some kilometers apart) near Longreach. I thought I had found a new species until I recognised the pattern to exactly match that of the Red-capped robin. The problem with both birds is that they were distinctly orange, not sort of, really orange. Like day glow orange. Are you familiar with a sub-species or local population with that variation?
