Sydney stadiums pay day close: Baird

NSW Premier Mike Baird says a number of Sydney's major sports stadiums are close to receiving their slice of a "once in a generational" upgrades funding package.

Mr Baird last year pledged $600 million for sporting venue upgrades in NSW, with Allianz Stadium, ANZ Stadium and Pirtek Stadium all vying for a slice.

Stadium owners have since been locked in long-running talks with the NSW government to maximise their share of the package.

With the state election over, the premier has now revealed pay day for the stadiums is not far away, fuelling speculation it will appear in the June state budget.

"We're not far away (from a decision)," Mr Baird said on Wednesday after a tour of Sydney Olympic Park with International Olympic Committee president Thomas Bach.

Mr Baird said the government is assessing the upgrades proposals of the major bidders to ensure the funding delivers the best outcome for sports fans.

"Obviously this is a once in a generational opportunity to upgrade some of our sports facilities," he told AAP.

"We've just got to make sure we get it right and put it in the right area."

In Sydney's inner-east, the SCG Trust wants to revamp its Allianz Stadium with a roof and state-of-the-art facilities as part of a planned Melbourne-style sporting precinct at Moore Park.

Across town, ANZ Stadium in Homebush envisions a modern rectangular ground with a retractable roof and moveable end stands to bring fans closer to the action.

Further west in Parramatta, Pirtek Stadium - home of Asian soccer champions Western Sydney Wanderers and the NRL's Parramatta Eels - wants to increase its capacity from 20,000 to about 32,000.

There is speculation the NSW government has considered giving about $300 million to Allianz, $200 million to ANZ and the remaining $100 million to Pirtek.
