North Queensland Cowboys full-back Kalyn Ponga gave Newcastle Knights fans a glimpse of what they can look forward to next season with a pair of tries against them in a 24-12 victory, while Gold Coast Titans overcame reigning premiers Cronulla Sharks.
Exciting 19-year-old Ponga will swap Townsville for Newcastle for the 2018 NRL season and was named man of the match after a scintillating display against his future club.
The Cowboys took the lead when Gavin Cooper barged over, but had to battle from behind after Brendan Elliot's 90-metre surge added to a score from Nathan Ross.
Ponga darted through a gap to pull North Queensland to within two points at the break ahead and he added his second after Kane Linnett carried two players over the line to ground the ball, with a Kyle Feldt penalty completing the scoring.
A pair of tries in the final 13 minutes from Leivaha Pulu lifted the Titans to shock 16-12 win against the Sharks - just their second victory of the campaign.
Gold Coast were boosted by the return of Jarryd Hayne for the first time since round two and took the lead after Tyrone Roberts created space in the Cronulla defence with a dummy.
Ricky Leutele barged over in the corner before the TMO ruled interference from Dale Copley denied Jayson Bukuya a chance to ground a kick from Chad Townsend and awarded the hosts a penalty try and consequently the lead.
But Pulu had other ideas, forcing his way in after great work from Konrad Hurrell before making the most of Townsend's failure to gather a grubber to rush over in the left corner and clinch the two points.
Corey Norman produced a sensational display as Parramatta Eels defeated Penrith Panthers 18-12, though they had to dig in to hold on for the win at ANZ Stadium.
Half-back Norman impressed with his kicking and touched down either side of a score from Semi Radradra as the Eels scored 18 unanswered points inside 45 minutes.
However, Parramatta - who lost Brad Takairangi to a suspected serious knee injury - became error-prone and were left clinging on after the Panthers hit back through Peta Hiku and Corey Harawira-Naera.
