A buyers agent in Mount Gambier is a licensed agent who acts only for the buyer, never the seller. Citadel Agency is a buyers agency based in Preston, Victoria, that helps investors buy in Mount Gambier and across Australia, with suburb research, on and off market sourcing, due diligence and negotiation through to settlement.
Consumer Affairs Victoria describes a buyer’s agent as a licensed estate agent who, for a fee, acts for a buyer instead of a seller. A selling agent works for the vendor. We work only for you: we find and shortlist properties, look at ones that are never advertised, check each one, and negotiate or bid at auction for you.
Citadel Agency was founded by Omar De Guise and Jadd Chahal. Every purchase is backed by our own suburb research, so your Mount Gambier decision is made on evidence, not on a sales pitch.

South Australia is led by Premier Peter Malinauskas (Labor), returned at the March 2026 state election. These are the changes that matter most to investors.
Mount Gambier is the largest city in South Australia outside Greater Adelaide and the hospital, health and services centre for the Limestone Coast, but its population grows slowly and about one in three homes is rented. We weigh that against supply and holding costs before recommending any Mount Gambier suburb.
