13 seconds to go.

Souths get it back and a penalty off the restart. Tense finish coming up.
Croker slots it.
Papalii - he may have just single-handedly taken Canberra into the final as he charges over!

Canberra have done it - they survive a pretty average set from Souths and then get a seven-tackle set.
This game has been flipped on it's head. Adam Reynolds takes the intercept and races away, is taken by CNK who strips it out and is binned! This will be a serious test for Canberra.
Canberra's goal-line defence - it has been incredible - they hold them out again but they need a penalty because that took a lot out of them.
This pressure is just ridiculous. Souths still don't look like breaking through as Canberra have been scrambling well and getting up in their faces. But Cody Walker forces a dropout. Again pressure on the home side.
Joseph Leilua off injured with Bailey Simonsson on to replace him as Souths threaten.
Canberra's defence has been unbelievable tonight but again they'll be under enormous pressure as Charnze Nicoll-Klokstad is dragged in-goal. Surely Souths crack them after multiple sets on the Raiders line.
Canberra touch an offload from Souths who get six again 40 out.
Canberra need a break here, they haven't had much of the ball but are defending brilliantly to make sure they hold Souths it. Maybe frustration will lead to a mistake from the visitors?

Canberra defendly astutely still but Adam Reynolds finds a way to force a dropout as Souths keep the pressure on.

We are 40 minutes away from deciding the first team who will be in the 2019 Grand Final.
HALF TIME - A frantic finish but still locked up at six points apiece - both sides have defended brilliantly so far and a tense finish to come.
Cody Walker beats a couple of defenders and is taken 20 out. Souths looming, but Jack Wighton takes the ricocheted kick on the last and races away. Dane Gagai chases his down, Canberra 30 out. They can't capitalise though as Aidan Sezer makes a mistake.

Croker can't land that one.
Jarrod Croker will shoot for two.

Jack Wighton kicks to Adam Doueihi on the last who is hit hard by Elliott Whitehead and Jarrod Croker in defence. Souths need to get physical here and aim up. Canberra are really putting their mark on this game early.
No mistake from Croker.

Josh Hodgson - concussed or not - he comes up with a one-on-one steal! Raiders 20 out.
Canberra need to play more direct here, their forward pack has always been a big strength but their going too sideways in attack. Jack Wighton now kicks it dead on the last.

Canberra caught out on the last as Jordan Rapana rushes a kick. Adam Doueihi bravely runs up to take it and is belted by Joseph Tapine and drops it. Raiders ball 20 out.

Adam Reynolds to the air on the last from 30 out or so and Charnze Nicoll-Klokstad rises above to take it.
Souths respond and defend that set well. Jack Wighton threatened with a surging run close to the line but outside of that just not slick enough from Canberra to crack them.

The dropout goes 60 metres on the fly - Souths not with as good a chance as the last set. They go over on the left edge through Alex Johnston but Campbell Graham passes off the ground. This will be Canberra's ball, they will take confidence from their defence on their own line.
Canberra scramble well early against some strong Souths attack. John Sutton charging to the line but stopped by Joseph Leilua and John Bateman. Liam Knight then straightens things up. Adam Reynolds now forces his second dropout of the game.

Canberra up to their 40 already on the second play. Iosia Soliola over halfway on the fourth. The crowd in it early. John Bateman with a nice run - 30 out as Jack Wighton kicks and Adam Doueihi is collared high but no penalty. A late call - penalty Souths.
Sam Burgess and Ethan Lowe with the first runs of the game. Canberra strong early in defence. Liam Knight bobbles it in the tackle but no whistle. Souths now throw it backwards and Campbell Graham dives on it. Not a great start from them. They're inside their own 30 on the last as Adam Reynolds clears it downfield.
Underway at GIO Stadium. Rabbitohs with first use of it.
A sold-out Canberra Stadium cheering on their side to a possible grand final appearance, their first in 25 years.
Will the Raiders finally stand up in the big games after a couple of disappointing past seasons? Or will Wayne Bennett bring the best out of a South Sydney side that wasn't at its best heading into the finals?
Canberra, on the other hand, are unchanged.
Souths have a raft of late changes. George Burgess is out, with brother Sam shifting to the front row, Tom back to the bench and Ethan Lowe into the starting side. Dean Britt also comes onto the interchange. James Roberts, as expected, is also out and replaced by Campbell Graham in the centres with Corey Allan on the wing.
