The Deputy Premier and Minister for Racing Bryan Green today officially launched the month-long Summer Racing Carnival at Tattersall's Park in Hobart.

Mr Green said the $2.5 million carnival starting in Hobart on January 20 will culminate with the AAMI Launceston Cup on February 27.

"The AAMI Tasmanian Summer Racing Carnival is one of the State's great success stories and has become an iconic event," Mr Green said.

"It generates significant and important exposure for the state's thoroughbred racing industry while delivering substantial economic benefits for the broader Tasmanian economy.

"It is a great way to promote Tasmanian thoroughbred racing to local and national audiences.

Mr Green said the carnival will again feature three night race meetings at The TOTE Racing Centre in Launceston.

"The Wednesday night meetings will be broadcast on Sky 1 which has a greater audience reach adding to the carnival's exposure.

Mr Green said the new TattsBet.com $100,000 bonus for the owner and trainer of any horse that can win both the AAMI Hobart Cup and the AAMI Launceston Cup would add even more interest to the carnival's two major races.

"Even though the last time this was achieved was in 2004 when the Peter Moody-trained Zacielo won both races, Geegees Blackflash went very close this year when he won the AAMI Hobart Cup and was just beaten by another Tasmanian horse, Previaling, in the AAMI Launceston Cup,.

Mr Green congratulated Tasracing, the Tasmanian Racing Club and the Tasmanian Turf Club for their hard work in developing carnival.
