North Queensland have locked down an NRL finals berth but it was ugly and it was late, the Cowboys grinding out a tense 20-19 golden point win over Cronulla in Townsville on Monday night.

The Cowboys moved to fifth on the ladder with the victory over a spare parts Sharks side but the match raised plenty of questions over the club’s premiership credentials.

Johnathan Thurston kicked two field goals to help claim the win, the first five minutes from fulltime before again being called to the fore in extra time.

Trailing 19-12 with four minutes to play, Cronulla scored a converted try through Sosaia Feki before Daniel Holdsworth booted a booming 45m field goal to lock the scores up with 24 seconds to go.

On paper, it was a monumental mismatch with the Cowboys boasting Test bookends Matt Scott and James Tamou, star playmaker Thurston and a host of in-form players across the paddock.

The Sharks went into the match gutted by the ASADA investigation into the club and an injury curse, with seven first graders suspended and another nine in the injury ward.

Add to that the sacked Todd Carney and retired Beau Ryan and there wasn’t much left for the club to even field a team.

And it looked as if the Cowboys would cash in, boom lock Jason Taumalolo scoring beside the sticks inside the first 90 seconds of the match.

But while the bookmakers had abandoned them, the Sharks came in full of belief and had the Cowboys stunned as they ran out to a 12-6 lead through tries to Pat Politoni and Feki.

Thurston’s class kept the Cowboys in the hunt, the captain earning his side two repeat sets before crossing himself to lock up the scores at the 30 minute mark.

Taumalolo snatched the lead back for the Cowboys in the 58th minute, wrestling his way through a sea of blue for another try sent upstairs to be adjudicated.

Thurston had seemingly iced the game with five minutes to play with his field goal, but Feki scored his double to keep Cronulla in the contest.

Holdsworth then silenced the 11,712-strong crowd when his second attempt at a field goal was successful.

While the win was ugly, it keeps North Queensland’s hopes of sneaking into the top four – and the double chance that comes with it – alive heading into round 26.

With a strong for and against record (+176 points) a spot in the top eight is a lock, the Cowboys now needing to beat Manly in the final round and hope Penrith lose to the Warriors to lock up fourth spot.
