A property developer and business partner of Mick Gatto has pleaded guilty in a Queensland court to receiving information from an insider at a Melbourne soccer club to place a bet that would have reaped $43,300.

John Khoury, 52, admitted to using inside knowledge to lay the $4000 multi-bet on a match between Dandenong Thunder and Melbourne City's under-20 team in the National Premier Leagues second division in August 2017.

It was alleged in the Southport Magistrates Court that Mr Khoury received a phone call about an hour before the game, when he was told that Dandenong Thunder was changing its line-up, including substituting some of its more senior players.

Mr Khoury, who was holidaying on the Gold Coast at the time, placed the multi-bet on Melbourne City's youth squad to win the match, combined with a horse winning in Queensland.
