Blayney Rams are locked into a switch to the Oilsplus Cup, three Shute Shield games are set to travel west and a CSU and Bulldogs derby will return to the field for the first time since the competition was restructured at the end of 2017.
Draws for the Blowes Clothing Cup, New Holland Agriculture Cup, Oilsplus Cup and South West competitions will be finalised this week but are believed to be virtually locked away, with the same six sides returning to the top tier.
Both women's and colts draws will be confirmed in March once team numbers are confirmed.
Three Shute Shield games will be coming to the region in 2020, with a standalone contest on Anzac Day in Cowra, when the Blowes Clothing Cup competition has a general bye.
Wade Park will again host an Eastern Suburbs home game, with West Harbour slated to play the Beasties on May 23 ahead of the Orange City and Emus derby under lights.
Mudgee will again host another Shute Shield match, this year on May 9, as Sydney Uni host Northern Suburbs at Glen Willow Stadium.
The Blowes Clothing Cup competition will kick off on April 18, with Dubbo Roos hosting Bathurst, Orange City travelling to Cowra and Emus hosting Forbes at Endeavour Oval in the opening round before a week off over Anzac Day.
The competition-wide bye means Cowra's Shute Shield match will be standalone.
Orange Emus won't have to wait long for a rematch of the 2019 grand final, with the greens set to travel to Ann Ashwood Oval to clash in Bathurst in round two on May 2, before the first Orange derby in May 5 as part of the Beastie's Shute Shield clash.
NSW County Championships will be held on June 6, leaving a competition-wide bye, with another week off after round 15 on August 15, giving a week between the end of the regular season and the start of finals.
The Blowes Clothing Cup grand final will be held on September 5.
Blayney Rams have confirmed a switch from the New Holland Agricultural Cup to the Oilsplus Cup and will face one of the longest roadtrips in the men's competition in its opening round as they travel to Coolah.
Trangie has also confirmed a return to the Oilsplus competition, while Coonabarabran won't take part.
Wellington and Geurie will line up in a grand final rematch in round two at Geurie.
Molong travels up the Mitchell Highway to open its campaign against Wellington before hosting Trangie, while Yeoval and Geurie clash in their opening round.
Finals will begin on August 8, with the grand final on August 22, which is the same date for the South West competition.
The slot left behind in the New Holland Agricultural Cup will be filled by a second tier Bathurst Bulldogs side, one expected to feature the bulk of the club's colts.
Bulldogs will clash with CSU Bathurst for the first time in round two on May 2, a week after travelling to Narromine for one of the toughest and most highly-anticipated New Holland Cup games in recent memory.
The Dubbo Rhinos play host to CSU in the opening round while Parkes welcomes Mudgee to town in the other opening fixture.
Finals in the New Holland Agricultural Cup start August 16, with the grand final locked in for August 29.
