Last chance ever to get a new points record in a single race.
Well, even if your amazing TT specialists do not succeed in breaking their own record, the current record will be very hard to break for any other country in the future. I estimate that the current Australian record (or new record this Sunday) will remain for a very long time.

The current record

=

Richard Levin (Aus) on his way to victory.
NT race 4, the time trial, Australian results = 1st, 3rd, 4th, 9th and 12th. This is a record total of 955 points ! 
Well done with all cyclists of your own team, Aurora Australis !
At the moment Australia is 2nd in the season ranking, just 205 points behind the Netherlands.
It seems to me that Australia is thé top favorite to become the world champion this season. 
About this last sentence, and this remark in your post :
we're now unbackable favourites to win the championship
True, because the Netherlands scored zero points in the previous exact same time trial.
And Australia is just 470 points behind at this moment.
Even when the best Dutch TT specialist can score a few points ( in previous TT he was 25th, just 1 second behind the points ), and Australia scores less points as in the previous time trial ; Australia will have a very good lead when NT race 7 starts.
And NT race 7 is on flat cobblestones.
That is perfect for Australia, because "on paper" we are better in flat cobblestones than the Netherlands.
Whether that will be the case in practice, we have to see. Maybe another GV as in the golden list because of the long distance and the 2 flat sections, and maybe there will be storm in this race what makes it tactical interesting and challenging.
But according to me the golden
flat cobble list can give a good indication ;
Australia; nr 3
Friend and the numbers 19, 36, 39, 60, 63 -
versus - the Netherlands; numbers 45, 46, 47.
Sometimes my predictions come true :

To me it seems the expectations are very high for season 7 ; Australia world champion again ? 
To me no doubt that Australia will achieve another very prestigious record ; the most points ever in one season of all countries.

And if Levin can win again, he will have the individual record of most points ever in one season of all cyclists.
But that is an "
if" at the moment.
First things first ; Levin has to battle with Jobet (FRA) for the individual world championship of this season.
In the previous time trial Jobet finished as 2nd on just 0:02", so he can be a fierce rival. Good luck, AA !
