In its most visible public transaction Allco was a part of Airline Partners Australia, the consortium that unsuccessfully attempted to buy Qantas.

The company is now in liquidation, after previously being in administrative receivership, following difficulties in refinancing debt and a share price fall of 99% since the beginning of the subprime mortgage crisis.

[1] Allco Financial Group was founded in 1979 by David Coe, a former partner of Sydney law firm Mallesons Stephen Jaques to originate and arrange structured finance transactions for aircraft, ships and rolling stock.

[5] In December 2006, Allco, along with several other firms, formed the Airline Partners Australia consortium as a bidding vehicle to Qantas although the deal failed in May 2007.

In December 2007 Allco led the acquisition by Australian investors of a series of power plants in the U.S. Northeast from Consolidated Edison, owner of New York City's electric utility, for US$1.48 billion.
