An emotional Forster, who secured the son of Rothesay for $28,000 2016 Magic Millions Gold Coast March Yearling Sale, paid tribute to the Nolan family, who bred the galloper at their Raheen Stud.
Raheen studmaster Basil Nolan Junior was tragically killed in a farm accident in early November.
“This is unbelievable,” Forster said.
“These sort of races don’t come around often and this little horse is just an absolute gem.
“No jokes aside, two runs ago he got a cold when Cadogan went past him and then we took him home and he was probably just unlucky the other day.
“It’s a bit tough too, Basil and Di Nolan bred this horse and they’ve done a fair bit for me.”
For South African jockey Mark Du Plessis, the victory was his most significant since making the move to Australia.
“There will be a handful of people in my life that will know how I’m feeling right now, to get a big one in Australia, it’s what I’ve always wanted to do,” Du Plessis said.
“Des has been a really good supporter of mine since I got here and to be honest, she was a big influence in me staying (in Queensland) so to do this for her and her owners is indescribable.”
