By champion sire Flying Spur, Alverta won the 2010 STC Coolmore Classic and her first three foals are all winners.
She was bought by Waller Racing and Guy Mulcaster, so will have every chance to succeed in Sydney's premier stable.
"She has a lovely pedigree and Deep Impact has been successful right around the world, not just in Japan," Mulcaster told Sky Racing.
"They are magnificent horses and they perform everywhere they go, so we're really happy to have her."
The filly is one of two in the sale by Deep Impact, the other from Charming Estelle will be offered as Lot 70.
