Master Lachlan Potts, 8, Casino, may have stolen the show but his Supreme Champion Boar of Show was edged out by the sow on the day.
A four-year 'veteran' of the show ring, Lachlan knows how to play to the crowd, harnessing applause like a seasoned professional.
His young Berkshire boar - Balmoral Stockman G 81, son of sire Riverglen Starman E113 and out of Balmoral Chantelle F73, aged four to six months - was beaten by the rather larger sow.
Best Pig in Show went to Riverglen Princess G77, aged nine to 12 months and sired by Aroora Expo 479 out of Gumshire Princess C184, exhibited by Richard and Heather Cole, Forbes.
The sow was the Supreme Exhibit (Group A) and Junior Champion Sow. The Coles were awarded Senior Champion Sow with Riverglen Princess D64 and Most Successful Breed Exhibitor.

Judge Grame Hopf, Murwillumbah, travels the world judging all types of livestock.
He said the level of competition was outstanding.
"The numbers are down but the quality is high given grain prices and labour costs," he said.
Mr Hopf said the junior boar was a "really good youngster and I have no hesitation he is the champion".
The junior sow was a "difficult class because the best pig ended up reserve because of injury". "But (the champion junior sow) is an outstanding type. Its fertility traits and teats are ideal.
"The Supreme exhibit was the closest decision I've had to make. I'm very proud of these two pigs."
Mr Kopf judged his 105th royal show in Australia with the poultry at Sydney Royal this year and has judged dairy, beef and carcases as well as the pigs.
