Our Story

Welcome. We’re Tony & Melissa Calder-Mason, and Greystone Estate is our labour of love — a place crafted for those who expect more than ordinary.

What began as a dream in 2018 has grown into something rare: a 10-acre sanctuary in the Hunter Valley, designed not just to host events, but to become a legacy. When you walk down our olive-tree lined driveway, you’ll feel it, every detail, every space, reflects the passion we poured into every stone, every suite.

Greystone sleeps 32 people, across 15 king-sized suites and 20 luxurious bathrooms, each private, each distinctive. Whether you’re stepping into the heritage charm of Gow House (originally from Merewether, lovingly restored), lounging by the deep pool beside the main house,or gathering under soft lighting on tue large verandah  — we designed it so every moment feels intentional.

We believe luxury isn’t about excess, it’s about refinement. Beauty in the way the light falls through the trees at sunset, in the hush before a ceremony, in the quiet of early morning when the whole estate belongs to you, your family or your guests. We curated Greystone so that when everything aligns: design, service, nature… time seems to stretch. You arrive with ordinary expectations; you leave with extraordinary memories.

We want Greystone to be more than an estate you visit. We want it to be the estate you dream of owning, the one you tell your friends about. Here, every wedding, retreat, and gathering all become stories.

We would love to welcome you to the Greystone family and share the memories with you.
