That's weird... my mum got her status extended for another year without even having to do any of the above. I was surprised she suddenly got an email about it.
I was very surprised too when I received the email extending my Silver status for 12 months, as I've been able to do sweet FA in the way of earning SC over the last couple of years. I haven't flown with VA since May 2021 (and that was only CBR-MEL-HBA), and rarely shop at Coles since we moved to Tasmania as there are three Woolworths stores that are easily accessible vs one old cramped Coles store so would have been lucky if I even earned a couple of SCs there, and I never transfer Flybuys points to Velocity either.
