Record-breaking Caulfield Cup winner Might And Power holds favouritism, at 4-1, for Tuesday's A$2.2 Melbourne Cup (3,200 metres) at Flemington.
There is increasing support, though, for Doriemus, who won the Cups double in 1995 with former Hong Kong jockey Damien Oliver in the saddle.
Doriemus, who this year will be ridden by the controversial Greg Hall, is 6-1 following his solid second in the Caulfield Cup. He will firm further - even possibly to favouritism - if the rain forecast eventuates.
Gai Waterhouse's Linesman is next at 7-1, followed by Lee Freedman's import Always Aloof at 8-1.
Arabian Story - owned by Queen Elizabeth II and prepared by Lord Huntington - is being quoted at 15-1 while Harbour Dues, who is in the stables of Lady Herries, is at 20-1 in latest markets.
Waterhouse has not relinquished hopes of starting her six-year-old Juggler in the International Cup.
