Here is the full roundup of all the action from the latest round of NRL fixtures.

Newcastle Knights 27-6 Brisbane Broncos
It was a dominant performance from the Knights who looked comfortable throughout as they improved their record to 4-1-1 to sit in second place on the ladder, trailing the Eels by just a point.
Meanwhile the Broncos - who have lost all four of their games since the restart - have slipped to 14th in the standings as the pressure begins to mount on Anthony Seibold.

Panthers edge out Storm in thriller
Penrith Panthers 21-14 Melbourne Storm
The Penrith Panthers continued their impressive start to the season as they edged past the Melbourne Storm in a fascinating encounter at the Campbelltown Stadium.
The boot of Nathan Cleary proved to be the difference as the Panthers half-back nailed all three of his conversion attempts as well as setting up Viliame Kikau for what proved to be the match-winner 18 minutes from time.
It was a frustrating defeat for the Storm and their head coach Craig Bellamy who said that his team needs to "decide who they want to be" in order to do well this season.
Dragons see off depleted Gold Coast Titans
Gold Coast Titans 8-20 St George Illawarra Dragons
The St George Illawarra Dragons eased some of the pressure on under-fire head coach Paul McGregor as they cruised past the Titans to move. up to 12th place on the NRL Ladder.
Zac Lomax contributed 12 of the Dragons 20 points as he grabbed a try, three conversions and a penalty goal against the injury-hit Titans, who remain at the foot of the table.
Tigers fly out of the blocks to see of the Cowboys

Credit to the Cowboys though who responded in the second half with four unanswered scores of their own but it proved to be in vain as they fell to a third-straight defeat to slip to ninth in the standings.
Roosters prove too strong for brave Eels
Sydney Roosters 24-10 Parramatta Eels
The Eels took a lead halfway through the second period when Maika Sivo tossed James Tedesco to one side to touch down but the Roosters showed why they are the best team in the competition as they came firing right back with scores from Boyd Cordner and Daniel Tupou as they claimed their fourth straight win to climb up to fourth place.
Injury-hit Manly see off out-of-sorts Raiders
Canberra Raiders 6-14 Manly Sea Eagles
The Sea Eagles picked up their most impressive victory of the campaign so far as they shook off early injuries to Dylan Walker and Brad Parker to pick up the two points against the disappointing Canberra Raiders.
The biggest concern for Manly will be the loss of the influential Tom Trbojevic who hobbled off in the second half with what looks to be a reoccurrence of the hamstring injury that kept him out of the opening rounds of the season.
Meanwhile, the Canberra Raiders will be hoping to bounce back next weekend when they come up against the Parramatta Eels in what promises to be a fascinating encounter.
