His pup almost upset the hot favourite last week, but Nowra Hill trainer Steve White knows Paua Explosion will be up against it to claim honours in the Group3 $25,000 Dapto Maiden Series (520 metres) final.

Four cracking semi-finals last week have helped assemble a talented field of youngsters for Thursday's final and White's kennel hope will need to defy the odds from box five to take home the loot.

"We are going to need plenty of luck but she is on the up," White said.

"She is going to need to ping the lids and lead. If she does, she is a chance of running a place because there is some really strong, young, good runners in the race."

White expected both the outside boxes to play a huge role in the finish.

Julie Fletcher's son of Milldean Panther and Mrs Trickett, Whittaker, will jump from box eight and looks the one to beat following a sizzling 29.55 win in last week's semis.

From the inside alley, David Pringle's litter brother to Wentworth Park track record holder Shakey Jakey - Master Shot - clocked 30.20 to romp home in his semi-final victory.

In the six box, Winsome Prince will look to avoid trouble at jump rise after he overcame difficulties to win last week's third semi-final.

The son of Barcia Bale and Winsome Shiraz chased down White's Paua Explosion in a time of 30.13 after running 29.77 a week earlier.

Paua Explosion ran second in 30.25 in the same semi to qualify for the final.

"It is going to be pretty hard from the five box. She has got ability but there are a lot of male dogs in the race," White said.

"She will get better as she keeps going, but could find it difficult this week."

While the focus this week will be on the Dapto Maiden Series, White has another plan in mind for up-and-coming star Tommy Brislane.

The trainer is hopeful of earning a start in the $75,000 Group1 Dapto Megastar next month after he prepared Amadeus Strikes for the same race a year ago.

"I have been trialling him there," White said.

"He has won nine out of 13 and ran second in the NSW State Sprint Championships.

"That will be the race we will aim at with him."
