Harrison outrode her allowance with her 80th winner earlier this year and with Gollan and other top trainers sticking by her, she has gone from strength to strength.
She won the Victory Stakes on Temple Of Boom in April and then rode the horse into second place in the Stradbroke Hcp (1400) last week.
Harrison has a great record on Brave Ali having steered the front runner on five occasions for four wins and a third and is flattered to be riding for trainers like Gollan.
"His horses are always well turned out and it is a big start. Brave Ali loves to roll along and that is the way we planned to ride him today," Harrison said on Saturday.
Brave Ali came to Gollan after he scored at Doomben in late March.
"Craig Martin trained him in Tamworth and left him with me after the Doomben win. I said to him that Brave Ali had won by three lengths and could only go backwards," he said. "But we have just kept the horse happy and he has done the rest."
It was a great training performance from Gollan because Brave Ali was having his first start in five weeks.
"We just kept ticking him over on the track and I felt he would run a good race if he had any luck today," Gollan said.
Brave Ali will now head to the Grafton Cup (2200m) on July 10.
Noisy Ocean ($14) finished fast to get second in the Ipswich Cup after giving the winner a start at the turn.
Grey Assignment ($9.50) matched strides with Brave Ali for much of the race and faded only in the final 50m to finish third.
Sydney galloper Ironstein ran on for fourth but jockey Jason Taylor said the horse's big weight had told in the final stages.
