Genuine galloper Megablast covered his upcoming travel expenses when he banked a tidy cheque for an emphatic victory at Ellerslie.

The son of Shinko King was untested to claim the thick end of the $30,000 on offer in Saturday's Shamrock Group 1600.

"That was a nice hit-out for him before he gets on the plane," trainer Nigel Tiley said.

Megablast is booked on a June 11 flight to Australia where he will be stabled with Cranbourne trainer Michael Kent for a two-start visit, which will serve as a forerunner to a Melbourne spring campaign.

"He'll run on June 17 over 2050 metres at Moonee Valley and we'll back him up a week later over 2500 metres at Flemington," Tiley said.

"He'll come home after that and go out to the beach before we get him ready again.

"All the better Melbourne horses will be up in Brisbane so it is the ideal opportunity for him to run around in a couple of handicaps and get the feel of the place."

Megablast was making his first appearance on Saturday since he finished fourth in the Gr.1 Auckland Cup in March.

"He wasn't out for that long and he's a better horse when he's in work," Tiley said.

Rider Michael Coleman gave the five-year-old an easy run in fourth spot one off the fence and Megablast coasted clear in the straight to win untouched by nine lengths from the stablemates Arzak and Bowie.

"He was jogging all the way and I just had to be patient and not to give him too hard a run first-up," Coleman said.
