Point of this post as I already mentioned is for it to be cautionary tale for those attempting to transit AU on two separate airlines who may not have a transit agreement in place
Australia is one of those countries that require a transit visa even if you complete your transit entirely air-side and never enter the country. I don't know how that interacts with the ETA scheme though.
