A buyers agent in Adelaide Hills 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 Adelaide Hills 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 Adelaide Hills 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.
The Mount Barker area added about 1,200 people in 2024-25, one of the largest gains in South Australia, and a new hospital, freeway interchanges and a planned school are following that growth. In the Adelaide Hills Council area only about one in ten homes is rented, so we weigh land supply and holding costs before recommending any Adelaide Hills suburb.

I have purchased multiple properties over the years however was stuck for over 6months trying to get into the Melbourne and Tassie market. I reached out to the team and in a few weeks they secured me 2 great properties. I will use Citadel for all future purchases going forward. 10/10
