I have finally had to get Qantas Industry support to clarify your
routing. ( even they are having trouble interpreting ).
He we go
J)WITHIN AUSTRALIA - ONLY O N E NONSTOP/SINGLE
PLANE SERVICE IS PERMITTED BETWEEN THE FOLLOWING
POINTS:
BNE/CNS/SYD-PER;
MEL/SYD-DRW.

This means that you can only have one sector when you get to Australia -
basically to finish your journey - this overrides the 4 sectors with SW
Pacific line.

So you need to reduce your Aussie flight down to 1 flight if you think
this is worth doing still.


And

When you are going over to Europe you can only transit one city if you
are not stopping - you have 2 cities you are transiting on Asia..

The rule is

C)ONLY ONE INTERCONTINENTAL DEPARTURE AND ONE
INTERCONTINENTAL ARRIVAL IS PERMITTED IN EACH
CONTINENT - EXCEPT AS FOLLOWS:
1)TWO PERMITTED IN NORTH AMERICA WHEN ONE IS A
TRANSFER WITHOUT STOPOVER. NOTE: TRAVEL BETWEEN
USA AND CANADA IS NOT CONSIDERED INTERNATIONAL;
2)TWO PERMITTED IN ASIA WHEN ONE IS A TRANSFER
WITHOUT STOPOVER OR ON DIRECT SINGLE PLANE
SERVICES BETWEEN THE SOUTH WEST PACIFIC AND
EUROPE;
