I know a few have mentioned this, but no-one seems to have spelt it out.
Will the current (admittedly, bargain) 30000 point Around Oz reward no longer be available under the new scheme or will it just be prohibitively expensive (points wise) as a result of the 10,000/stopover?

As an example, I recently took an award flight SYD-MEL(stopover)-WLG-SYD for 30,000 points. My calculation under the new scheme for this itinerary is 70,000 points - a 133% increase!! Is this right? If so, then it's ridiculous. A straight SYD-WLG-SYD would still be 30,000 and a SYD-MEL-SYD would be 20,000 so 2 separate itineraries would 'save' 20,000 points (70,000 - 50,000) yet involve an extra flight segment. In other words the argument for charging 10,000 per stopover to free up seats seems a bit shallow when, in this case, it would be cheaper (in points) to take an extra unneccessary flight segment.

BTW: Thanks, Bruce for your input - you have concisely answered a lot of queries.
