2018 NRL try-scorers: David Fusitu'a still leads after round six, but Matt Dufty closes the gap

The St George-Illawarra Dragons appear to be at the top of almost every list during the start to the 2018 NRL season.

The Red V took care of the Sharks 40-20 on Friday, and young fullback Matt Dufty scored a double in the process to take his season total to six.

Storm wingers Josh Addo-Carr and Suliasi Vunivalu look like they are returning to the form that tore up the competition in 2017, and both scored two tries each in Melbourne's huge victory over the Knights.

Despite the big loss, Newcastle winger Ken Sio managed a brace of his own.

Elsewhere, Jamayne Isaako crossed the line twice in the Broncos win over the previously unbeaten New Zealand Warriors.

Panthers second-rower Corey Harawira-Naera scored two against the Eels, while NRL veteran Benji Marshall tore up the Sea Eagles at Lottoland and crossed for a couple of meat pies.
