Outside of her work at OakTree, Kirsty enjoys being a busy mum, cheering on the Vixens and Geelong Cats and more often than not chauffeuring her children around to their various activities with an almond latte in hand.

Alfie & Dukey

Wellness Coordination Team

Alfie and Dukey, the Office Dogs and wellness extraordinaires, bring joy and comfort to the workplace.

These matching Toy Cavoodles, who both believe they’re human, play a key role in spreading happiness by offering endless cuddles.

When they aren't brightening the office, they are enjoying zooming around and indulging in their favourite pastime—dining out at local cafés.

Together, Alfie and Dukey also have a penchant for getting into a bit of office mischief and sleeping on the desks.
