BERNBOROUGH was bred at Dalby in Queensland by Harry Winten and sold as a yearling for 150 guineas to Frank and John Bach.  The Queensland Turf Club refused to accept nominations of horses owned by the brothers so Bernborough was sold to A E Hadwen.  The QTC suspected an association with the Bachs so consequently Bernborough could not race in the city and had to race for four years around Toowoomba in the Darling Downs.  At two years he had 5 starts for 4 wins and a second.  At his last appearance as a two year old he carried 9st 9lbs but still won easily.  At three, he had four starts and won them all.  Then he developed what was thought to be a shoulder injury and at four lost both his races while at five started 8 times for 3 wins and 1 second.  At the close of his five year old season, Mr Hadwen decided to sell the horse as he still could not start on city tracks.  Bernborough was sent to Harry Plant, a Sydney trainer, to prepare him for sale.  Plant was not convinced that Bernborough had a shoulder injury and felt it was foot problems.  He had a farrier inspect the horse, and after paring back his hooves found he had deep-seated corns.  Ten days later Plant secretly trialled the horse who ran an outstanding trial.  Bernborough was entered in a barrier trial which he won easily.  Plant decided to buy the horse but he was finally "knocked down" to Azzalin Romano, a Sydney nightclub owner, and friend of Plant for 2,600 guineas.  The QTC at first refused to lift the ban but finally relented.  He had his first Sydney start at Canterbury in December 1945 with jockey Noel McGrowdie.  Plant instructed the jockey to let him settle but bustled him from the start and on the tight track he gave away too much start but flashed home for fourth.  In his next sixteen starts he was ridden by Athol Mulley.  His next start in the AJC Villiers Stakes saw him win easing down and then he went on to win his next 14 wins in succession, including the VATC Futurity Stakes, the Newmarket Handicap with 9st 13lb.  Then followed the Rawson Stakes at Rosehill, Chipping Norton Stakes, All Aged Stakes.  His next assignment was to be in Brisbane in the Doomben Ten Thousand over approx 7 furlongs and the Doomben Cup over 11 furlongs.  In the sprint he was allotted 10st 5lb and opposed by 26 other top-class sprinters.  He sat 5 and 6 wide and came from last at the turn to win by 2 lengths in race record time.  A week later he was penalised 10lb and carried 10st 11lb in the Cup.  After being tailed off last he stormed home to win easily.  His next start was the AJC Warwick Stakes, followed by the Chelmsford Stakes, Hill Stakes and Caulfield Stakes, all of which he won easily.  In the Caulfield Cup he was given 10st10lb.  Bernborough was never out of trouble in the run and half way down the straight he was still well back.  He flew home for a close fifth.  There was criticism of Mulley's ride so he was replaced by Billy Briscoe.  In the LKS McKinnon Stakes he was travelling comfortably when he tried to jump the straight six crossing and fractured a sesamoid bone.  He was given immediate veterinary attention and it was felt he could be saved for stud.  Altogether he won 26 races.  Mr Romano sold Bernborough to Louis B Mayer, of MGM to stand at Spendthrift Stud Farm, Kentucky.  At stud he sired the winners of over $4.5million including Berseem, Bernwood and the sire Hook Money.
