Does the Qantas grounding show internal division within the oneworld alliance?

The recent QANTAS grounding surely shows the internal division within the Oneworld alliance. I would have thought at the very least BA would have been utalised to prevent the passenger shambles in London and Asia(for everyone other than travelling in first). Surely BA had spare aircraft and aircrew to run those sectors sitting at Heathrow, even if delayed, if A Joyce had wanted them? Would have been a far better outcome (PR and in practice) for Qantas and Oneworld. Imagine if this had happened next year after BA and Qantas split up the kangaroo route. As for Cathay - didn't see them offering much help either. Thoughts?

Rather than internal division, I would say BA and CX didn't intervene or assist because they didn't want to create trouble meddling in the IR affairs of a member carrier. Or trouble with the Australian unions for "scab" labour.

Why would the alliance partners be obliged to help Qantas out? The airline isnt unable to fly their passengers, they are just actively choosing not to.
