The Brighton Army Barracks, now worth $35 million, were sold by the federal Liberal government in 2003 for $150,000 despite a valuation of $2.4 million.

Greens Leader Bob Brown asked Defence Minister John Faulkner today in the Senate how the Valuer General could have got the valuation so wrong.

Senator Brown called for a review of policy on the sale of land to prevent such a debate in future.
