Wave 4 Hypersphere Dual Packs In Australia?

I was wondering if the wave 4 Hypersphere dual packs ever released in Australia because I’ve never seen them here ever. All I ever see is the wave 3 dual packs the past 2 years.

I’m really confused about it, we’ve had the Lord Spryzen dual pack for a while now but no Shield Kerbeus or Master Devolos?
