About Us

Trusted Real Estate Partners in Thailand

At Siam Property Group Australia, we understand that buying property overseas can be both exciting and overwhelming. Founded by Sean Prosser, a licensed financial adviser with over 25 years of experience in helping Australians plan their financial futures, our mission is to bring clarity, confidence, and professionalism to international property investment—starting with Thailand. Sean has spent decades guiding clients through complex financial decisions, retirement planning, and long-term wealth strategies. That same trusted guidance now extends to helping Australians navigate the unique challenges of buying property abroad. Whether it’s sourcing the right property, negotiating with developers, or managing legal requirements, Siam Property Group is here to simplify the process and protect your interests. While we do not provide legal or tax advice, we act as your dedicated project manager throughout the journey. We ensure you're connected with experienced, reputable professionals—lawyers, tax advisers, and other specialists—so that every step is handled with care, compliance, and confidence.

Why Work With Us

We’re more than just advisors — we’re your full-service project managers on the ground in Thailand. With a deep understanding of both Australian and Thai property markets, we bridge the cultural, legal, and language gaps so you can buy with clarity and confidence.
