But the win appears to have come at a major cost with five-eighth and co-captain Mark Gasnier being forced from the field with a shoulder inury in the 63rd minute.
The extent of the injury is yet to be fully determined but reports indicate that Gasnier has a torn pectoral muscle, often a season-ending injury.
A Telstra Stadium crowd of over 20,000 were in attendance to see what is widely recognised at the unofficial start to the rugby league season.
With numerous new recruits on show for both sides, the Rabbitohs appeared to have the strongest team on paper with seven internationals taking the field. The Dragons named a side of relative unknowns with a number of rookies replacing injured regulars.
Prior to being injured, Gasnier's move to five-eighth appeared to deliver the desired results with the former international centre proving a handful close to the ruck and giving good service to his outside men. But following a tackle on Nigel Vagana in the 63rd minute, Gasnier left the field and ran straight up the tunnel clutching at his right shoulder.
South Sydney opened the scoring after just four minutes when back rower Luke Stuart ran onto a beautifully timed pass from half back Joe Williams close to the line. Williams converted and the Rabbitohs were 6-0 in front.
The Dragons struck back in the 22nd minute through centre Wes Naiqama. Dummy half with new recruit Simon Woolford exploited a simple decoy play to find Gasnier in the backline. The ensuing overlap saw a bullet pass from Gasnier to Naiqama who finished well to touchdown out wide.
An unsuccessful conversion attempt followed and the Rabbitohs were up by 6-4.
The Dragons hit the lead soon after courtesy of another backline movement, rookie full back Josh Morris chiming in and finding space from 15-metres out.
Naiqama had little difficulty with the conversion and the Dragons were 10-6 in front coming up to half time.
Souths responded with some entertaining football and were rewarded just before the break. Following a knock-on by 17-year-old Dragons winger Chase Stanley, the Rabbitohs capitalised with a David Peachey trademark flick pass behind the back and onto forward David Kidwell who offloaded close to the line. Shannon Hegarty swooped on the loose ball to score, the video referee checking for a knock-on and giving Souths the benefit of the doubt.
At half time it was 10-all.
The scores remained deadlocked before centre Nigel Vagana scored midway through the second half. Once again the Rabbitohs were given benefit of the doubt by the video referee after the ball was batted down by Peachey. Vagana was on the spot to score adjacent to the corner post.
Williams was unable to convert and with 20 minutes remainng, Souths were 14-10 in the lead.
With Gasnier off the field and Souths gaining the ascendancy, it appeared that the Bunnies were set to retain the Shield. But a wayward pass from Williams to David Fa'alogo saw Hornby pounce on the intercept and run 70-metres to score the winning try.
