Can one redeem more than one Star Alliance Business Class seat using Krisflyer miles?

Hi folks, Hoping to pick your brains yet again. I am in need of 4 business class seats from Sydney to Japan and have realised it is fairly impossible to find- the ideal route I would like to fly is direct hence using Krisflyer points to redeem its Star Alliance ANA flights. I can only manage to find 1 business class seat for this flight. Has anyone managed to redeem more than 1 star alliance seat with Krisflyer or is there a magical way I can work towards getting at least 2 seats?

Many thanks
Catherine

Some airlines might limit the available award seats on partner programs. But usually, there is nothing magical about it. If there are 2 available seats on your program, they will let you book it.

For example, Thai Airways showed 2 more seats after I booked the first 2 seats. There are slight oddities like that but not very common.
