Founded by the Matthews family in 2024 as the successor to the Guy Matthews Hotel Group, Piermount Group unites a collection of iconic South Australian venues—including The Stirling, Marryatville, Albion, Seaton, and The Australasian boutique accommodation in Goolwa.

A family-owned hospitality leader with eight decades of experience, Piermount recently secured approval for a $30 million new tavern in Mount Barker—the first such greenfield project with a gaming licence in over 150 years—marking a major expansion milestone.
