Yes sorry I wasn't more clear. I explained that I had two separate PNR's however the first PNR for SYD-ADL was a redemption ticket and I showed the screenshots about the exclusion for redemption tickets. The check in agent called over a supervisor who made a phone call and said that that exclusion no longer applies and the info on the website is now outdated.

My bag was only checked as far as ADL.

It was no major deal. The main reason I wanted it checked through to DOH was I had built in extra buffer time at ADL knowing I was on a separate PNR ADL-DOH so had around six hours at ADL airport. If my bag could have been checked through to DOH I would have landed in ADL and jumped in a taxi and had a look around the city for a couple hours. Eh ho.
