Lines to get into the Rabbitohs' spiritual home snake halfway around the block after Souths ended their 43-year title drought with a 30-6 win over Canterbury in the grand final on Sunday night.
The streets around Redfern Oval are awash with red and green and chants of 'South Sydney' can be heard from blocks away.
Around 10,000 fans are expected to attend the celebrations.
Clive Churchill Medallist Sam Burgess is expected to take part in the celebrations, despite fracturing a cheekbone in the first tackle of the grand final.
Burgess will undergo surgery on the injury on Tuesday.
Meanwhile South Sydney owner Russell Crowe has presented suspended Kiwis hooker Issac Luke with an NRL Premiership ring he bought for him, after the Rabbitohs' grand final win over the Bulldogs.
Luke missed the game through suspension for a dangerous tackle on now-former Sydney Roosters star Sonny Bill Williams in the semi-final, and the hooker will also sit out the upcoming Four Nations clash with the Kangaroos.
Crowe hailed the contribution of his players and staff after the club sealed a first NRL Premiership in 43 years at ANZ Stadium.
The Hollywood superstar, who bought into the club in 2006, says it was a night he will never forget.
Crowe helped restore the club to being one the the game's superpowers 12 years after they were readmitted back into the competition.
He says there's deep deep satisfaction, this is a team sport and there has been a lot of people involved over the last nine years and a lot of effort gone in.
Crowe calls the victory a grand reward for those who stepped up to the plate and said Souths weren't to put up with being a losing club any more.
