The Bet On Birdsville promotion has raised at least $50,000 to help drought-stricken Queensland farmers after the historic country meeting was broadcast and televised nationally for the first time.

It follows an earlier racing function in Brisbane which raised $47,500 for drought aid.

Racing Queensland pledged to donate half its wagering revenue generated by the two-day meeting at Birdsville, 1600km west of Brisbane, to the Queensland Drought Appeal.

There was also an associated digital promotion to highlight the fund raising drive.

Racing Minister Stirling Hinchliffe said the result had been terrific and a credit to the racing industry.

"Thousands of visitors flock to Birdsville each September to experience Australia's most famous outback race meeting," Hinchliffe said.

"This year, thousands more around the country were able to watch the races live and have a bet, and in doing so help Queensland's struggling farmers."

"It's a terrific result for drought-affected communities throughout Queensland, with $50,000 raised through the Birdsville Cup. "

Racing Queensland's Thoroughbred General Manager, Simon Stout said the 2018 Birdsville carnival on Saturday and Sunday was an outstanding success, uniting people from all walks of life.

"While wagering numbers are still being finalised, thanks to the support of racegoers nationwide, RQ will be donating at least $50,000 to the Queensland Country Women's Association," he said.
