Events of last year have inspired jockey Dwayne Dunn's confidence he can spring a Queensland Derby upset.

Dunn will travel from Melbourne to Brisbane on Saturday with the sole purpose of riding $21 chance Happy As Hell at Eagle Farm.

A year ago, Dunn steered Electric Fusion into second behind the Chris Waller-trained Hawkspur and the jockey drew parallels when he assessed Happy As Hell's hopes of going one better.

Both Happy As Hell and Electric Fusion were placed in their final lead-up runs at Sandown before heading north.

"I don't see why he can't win drawing a line through Electric Fusion," Dunn said.

"Electric Fusion ran second in the race last year coming off a Sandown run and he drew the outside barrier."

Happy As Hell finished third behind the promising import St Jean over the Derby distance at Sandown last Saturday, which Dunn said left the Terry and Karina O'Sullivan-trained gelding ready for his Eagle Farm test.

Dunn had no doubts Happy As Hell would see out the 2400 metres of the Queensland Derby and nominated the three-year-old as capable of winning races such as the Adelaide Cup in coming seasons.

"His asset is he stays and he's been about the older horses but he's untested at this level," Dunn said.

"The trip suits him but he is unknown that way of going."

Brambles was the last Victorian-trained Queensland Derby winner when he took out the race for Peter Moody in 2012.

The Troy Corstens-trained Pinstripe Lane is the highest Victorian entrant in Queensland Derby markets as the $4.80 equal second favourite.

Vilanova is the $4.50 favourite to give premier Sydney trainer Waller his second consecutive Queensland Derby win.

Waller has a strong hand in all three Group One races at Eagle Farm with Red Tracer a prime candidate to win the $1.3 million Stradbroke Handicap while her stablemate Velrosso is a confirmed starter and Masthead the first emergency.

The Waller-trained Brazen Beau is the favourite in the JJ Atkins for two-year-olds.
