Just ask Nick Olive who will chase his third on Sunday with star stayer Pecuniary Interest, looking to replicate previous stable triumphs by Predominance (2008) and Voice Commander (2011).

Or legendary Queanbeyan trainer Frank Cleary, who had to wait until 2009 when Bomber Command saluted to finally drink from his home-town Cup at the age of 61. He memorably serenaded adoring locals with a version of John Denver's 'Some Days are Diamonds' in the immediate aftermath.

His son Joe won it twice in a row with Landlocked (2014) and Hudson County (2015) but has also not quite yet been able to capture the elusive hat-trick.

He'll have another go on Sunday when he unleashes Savabeel five-year-old Havaduel who has notched three wins for Cleary since moving up from Victoria almost a year ago.

But it's Olive's Pecuniary Interest they all need to beat, so long as the horse bounces back from his disappointing last-start showing in the Country Classic (2000m) at Rosehill.

"His run the other day was ordinary, he led, went at a good tempo and compounded so we'll be riding him a little bit quieter than that on Sunday," Olive said.

"Hopefully back to this level he can bounce back."

Regular partner Ellen Hennessy returns to the saddle, and her 1.5kg country claim brings the horse's weight down to 57.5kg.

Pecuniary Interest won the Bathurst Cup (1800m) three starts back with Hennessy in the saddle, who has piloted in three of the four-year-old's five wins.

Olive is hoping for a big day at Queanbeyan, aiming to take out the Thunderbolt Handicap (1000m) with Polar Star who is also coming off a disappointing last start at Wagga.

"He'd been racing so well before that so we put him in the paddock for a week after last run and just tried to freshen him up a little," Olive said.

"I thought he worked really good on Tuesday so hopefully he can run a better race too."
