Big Brother's New Contestant Holly Young Has a Notable Past Relationship

Sydney influencer Holly Young made her reality TV debut during the recent return of Big Brother Australia. Fans might be surprised to learn that she previously dated one of Australia's leading luxury real estate agents.

Relationship with Gavin Rubinstein

Daily Mail revealed that Holly was romantically involved with Gavin Rubinstein, a star of Luxe Listings Sydney. The couple went public in August 2024, sharing affectionate holiday photos, but their relationship ended quietly a few months later.

"Things got complicated when they started travelling together," an insider said. "It was fast-paced from the beginning, but they were just in different places in life."

Sources close to them explained that an intense overseas trip exposed underlying issues beyond the glamorous facade.

After the Split

Following their breakup, Holly had a brief relationship with entrepreneur Richie Harkham, who is a close friend of Rubinstein. The pair were seen spending Christmas together at his family's Hunter Valley winery.

Meanwhile, Rubinstein, previously the No. 1 seller at Ray White, went on to establish his own luxury real estate firm, The Rubinstein Group, and celebrated the New Year in New York City without Holly.
