Former Camden MP and Camden mayor Geoff Corrigan could be seen jumping for joy at this year's Melbourne Cup.
His horse, Vow And Declare has held off the international challenge to win the Melbourne Cup, giving jockey Craig Williams his first success in Australia's greatest race.
Many Macarthur residents and politicians took to Facebook to congratulate the former Labor politician.
"Congratulations Geoff Corrigan! I'm also a winner today," she said.
Brianna Thurston posted her well wishes to Corrigan and his family.
"Wow wow wow! Congratulations Geoff Corrigan and Sue!!" she wrote.
"What an amazing achievement to not only get Vow and Declare into the cup but to go on and win it!!"
Keira MP Ryan Park took to Facebook hours before the race to wish his former Labor colleague luck.
"Good luck to Geoff Corrigan and his family who are owners of Vow and Declare," he posted.
"Geoff was a great Labor MP and I hope he can be just as successful in today's race that stops the nation! Get on it!!"
The win was also a first for trainer Danny O'Brien with Vow And Declare crossing the line ahead of Master Of Reality, Prince Of Arran and Il Paradiso whose jockey Wayne Lordan lodged a protest against the runner-up for interference in the final stages.
Williams famously missed the winning ride on the French-trained Dunaden in the 2011 Melbourne Cup because of suspension.
Eight years later, Williams joins Neville Sellwood, Roy Higgins, Pat Hyland, Mick Dittman, Jim Cassidy, Damien Oliver and Chris Munce as the only jockeys to win the "grand slam" of Australian racing - the Golden Slipper, Caulfield Cup, Cox Plate and Melbourne Cup.
In a desperate finish involving four horses, the Danny O'Brien-trained Vow And Declare took an inside run and put his head down when it counted to win in a photo finish.
For O'Brien the win was one that meant everything.
The trainer was involved in a protracted battle with officials over a cobalt case which he eventually won but the process took its toll on his business.
"It doesn't get much better than this," he said.
