Ryan Papenhuyzen made sure the Storm celebrated coach Craig Bellamy's 500th NRL match in winning fashion, with a golden-point field goal sealing a dramatic 15-14 victory over South Sydney in Melbourne. 

Papenhuyzen's effort came after a stunning two-point field goal from South Sydney star Latrell Mitchell in the dying seconds pushed the match into extra time for a golden-point showdown.

Making his return from suspension, Mitchell was mostly disappointing and missed three conversions but he stepped up when it mattered with his drop-kick from 45 metres out sailing through the posts.

The Storm had earlier produced a dominant first-half display, scoring three tries to lead 14-0.

But it all unravelled in the second half as South Sydney surged back into the match, scoring three tries in nine minutes to set up a thrilling finale.

Winger Alex Johnston scored in the 68th minute and Jaxson Paulo crossed with six minutes remaining.

Campbell Graham's 77th-minute try sent a hush over the Melbourne crowd, who had been ready to start the celebrations for their beloved coach.

But Papenhuyzen made certain the champagne corks could start popping and continued the Rabbitohs' winless streak in Melbourne.

Despite the win, Bellamy struggled to muster a smile, with his team surprisingly missing 40 tackles.

The Rabbitohs' attack, meanwhile, looked rudderless for much of the match in the absence of former halfback Adam Reynolds, who is now with Brisbane.

His replacement Lachlan Ilias kicked out on the full 40 metres out from the try line, with Papenhuyzen scoring in the next set of six tackles.

But that was all the home side could manage as their attack fell away until Papenhuyzen got his kick away to seal their second win of the season.
