A Sydney real estate agent has admitted the ultimate buyer of four trophy homes was not a 32-year-old Chinese-born Australian, Zhang Bo, as shown on the title deeds.

The admission will renew pressure on the federal government to tighten scrutiny of foreign investment rules, after AFR Weekend revealed on Saturday that Mr Zhang owns six properties in Sydney’s Mosman worth $37 million, but lives in none of them.

The agent who sold four of these harbourside houses, Richard Simeon, confirmed all were bought by different people, even though three of them are held through one company and all are linked to Mr Zhang.
