Velocity points earned from flights higher than expected - is there a promotion on?

Hi,
I flew VA this week and checked my points activities to see a larger than normal bonus applied.
CBR>MEL via SYD.
I have never taken this leg before. Normally I experience a 75% bonus from Gold status, but on this week flight it is close to 272% for each flight.

Is there a promo / something I am not aware of?

I don’t know of any promotion, but experienced the same:

Base Bonus Total
996    2,738   3,734

I haven’t read of any promotion.
