Daryl Douglas is confident Make Mine Cullen will receive one of two invitations remaining for the Miracle Mile in Sydney.
Douglas, the leading reinsman in Victoria, is the driver of Make Mine Cullen, trained by his brother Glenn.

He has been the leading reinsman in Victoria the past five seasons with a record 338 wins in a season.
The 36-year-old has driven 3600 winners.
Glenn has been the leading trainer for Victoria the last three seasons.
The Miracle Mile is at Menangle on November 27.
The Douglas brothers were at Oamaru yesterday representing Australia.
