Kingston replaces Jeff Kendrew who resigned in order to join Brookfield Asset Management as chief development officer.
Prime chairman Dr David Hamill said Kingston brought with him a wealth of infrastructure management experience.
Kingston helped refinance more than $A3 billion of debt in 2008 and 2009 for Brookfield Multiplex.
Prime changed its name from Babcock & Brown Infrastructure in November, with the company giving up a 49.9% stake in the Dalrymple Bay Coal Terminal to Canada’s Brookfield Asset Management under a $1.8 billion recapitalisation.
DBCT exported 32.1 million tonnes of coal in the six months to the end of 2009, 24% or 10.4Mt lower than what would be expected of an 85Mt per annum terminal in this period.
