Just minutes after he sprayed what would have been a match-winning conversion in regulation time, Dylan Walker nailed a long range penalty goal to break green hearts.

Moments earlier Canberra skipper Jarrod Croker was wrapped up with two unmarked green jerseys on his outside on the last tackle, a play after Blake Austin went within a whisker of the line.

The Raiders were seemingly one Croker pass away from victory, but instead left green with envy.

How quickly a match can change

Blink and you'd have missed it. That's how fast the tide was turning in the second half.

Canberra's defensive resolve was tested relentlessly in the first half, but having weathered the storm and scoring the first try of the second half it looked like the Green Machine had some new wheels.

But if Manly showed anything in their four-point loss to Melbourne in round seven, it was that a Sea Eagle's wings are tough to clip.

Trailing by 10, Jake Trbojevic and Dylan Walker bagged tries in a four-minute period to steal the lead.

Jordan Rapana struck back, before Tom Trbojevic stole a late try to level the scores before the stunning extra-time finish.

Manly added another huge scalp to an impressive away resume featuring wins over North Queensland and the Sydney Roosters.

Rapana's highlight reel just gets better

Just when you think Rapana and Joey Leilua have had an unusually quiet day at the office, they do the impossible.

With the game on the line, Rapana raked a grubber in from over the dead ball line and grounded it just inches from the line in one of the most remarkable tries of the season.

Much of the talk during the week centred around Canberra's lethal right-edge attack clashing with Manly's "passive" left side defence.

"Leipana" didn't fire like many had hoped they would, Rapana's moment of brilliance the only real highlight of the night for Canberra's right-edge.

But it was a moment that ended any arguments about Canberra's being the best right edge in the NRL.

It was their 19th try on the right side this season, seven more than any other team in the NRL - the proof is in the pudding.

Premier Papalii

Rampaging Raider Josh Papalii is the best back-rower in the NRL - no ifs, ands or buts about it.

Papalii all but confirmed his spot in Mal Meninga's Australian side that will play at Canberra Stadium on May 6 as he continued his run of career-best form.

The softly-spoken giant left two Manly defenders in his wake and carried another two over the line for the first try of the second half in a glimpse of brilliance.

Clydsdale locked in the stables again

After being locked in the stable for the entire 80 minutes last week, Raiders back-up hooker Adam Clydsdale spent all of regulation time riding the pine pony against Manly.

Spending 160 straight minutes on the bench clouds Clydsdale's role in Canberra's NRL squad, and makes one wonder about Ricky Stuart's plans for the back-up hooker, who eventually saw five minutes of action in golden point.
