An undisclosed honorary membership to the Marrickville Golf Club given to Prime Minister Anthony Albanese was actually worth $1,100, not $5 as Mr Albanese claimed.
The club's management also said the $6.05 million grant value was based on a "guesstimate" of what its proposed upgrades would cost.
An inquiry into the grants program under which the golf club was funded is continuing.
Marrickville Golf Club's management says the honorary membership it gifted Prime Minister Anthony Albanese granted full access, putting its worth over $1,000, far more than the $5 social membership Mr Albanese claimed he was conferred.
The club's management also admitted the $6.05 million grant it was awarded by Mr Albanese was never intended to fund sewerage fixes, which are being done under a separate NSW grant.
Earlier this month, Mr Albanese conceded he was wrong when he told the House of Representatives that the grant he had promised the Marrickville Golf Club at the 2025 election was to stop septic tank sewage flooding into the river.
"When it floods in Marrickville, raw sewage flows into the Cooks River. That is what the funding is for," Mr Albanese told the House of Representatives in September.
General manager Mathew Ward, however, said sewerage upgrades were never part of the federal grant.
