Autumn carnival punters are on the verge of cashing in for the second time in seven days on a glamour mare of the Australian turf.

Professional and rank-and-file punters who won on the unbeaten Black Caviar are now preparing to line their pockets with further short-priced winnings on More Joyous.

More Joyous will go to the barrier for Saturday's $2 million Doncaster Mile as one of the hottest favourites in the famous race's rich history.

She is quoted as short as $2 with TAB Sportsbet and not even a disastrous result at Tuesday's barrier draw will result in a dramatic shift to the dynamics of the market.

"More Joyous is easily our worst way, especially with doubles and other multis kicking in," TAB Sportsbet's Matt Jenkins said.

One TAB Sportsbet punter was quick off the mark, investing more than $3000 for a $40,000 collect on Black Caviar winning the Newmarket Handicap and More Joyous taking out the Doncaster.

Black Caviar opened at $2.30 before winning the Newmarket as a $1.18 favourite.

More Joyous was a $7 chance in TAB Sportsbet's first Doncaster markets.

She has also been coupled heavily with Blue Diamond and Golden Slipper winner Sepoy.

There is also a cross-code double alive for a return of almost $37,000 with last week's Inter-Dominion Trotters Championship winner I Can Doosit.

More Joyous will be going for her 11th consecutive Sydney victory - a sequence which started with her Tea Rose Stakes win at Rosehill in September, 2009.

In latest AJC Australian Oaks betting, Shamrocker continued to attract most support on Monday.

Fresh from beating the colts and geldings in the AJC Australian Derby, Shamrocker has overtaken Brazilian Pulse as outright Oaks at $3.20.

"Brazilian Pulse has been friendless with us with Fibrillation the second most popular Oaks runner in terms of percentage of investment," Jenkins said.
