This.
Premise being that you wear your main/home jersey as much as possible, who that would clash with on the road:
Brisbane - Manly, Dolphins, to a lesser extent Penrith, Tigers, Cowboys, Roosters
- current away jersey probably makes sense - white and gold
Canberra - Souths
- current away jersey probably makes sense but is being worn against teams it doesnt need to be; mostly navy would probably also work
Canterbury - Saints barely
- current away jersey does the job
Cronulla - Titans barely, maybe Canterbury, Saints
- current away jersey (black) is a good contrast option for games against teams with lighter jerseys
Gold Coast - Sharks barely, maybe Parra
- current away jersey is probably ok, although a yellow one would be fairly unique (see Magic Round)
Dolphins - Broncos, Manly, to a lesser extent Newcastle
- current away jersey is ok but they could probably use the sand/mustard colour whatever it is more
Manly - Brisbane, to a lesser extent Penrith, Tigers, Cowboys, Roosters, Storm
- current away jersey probably does the job
Melbourne - Parra, Warriors, Cowboys, Roosters, Penrith, Manly
- current away jersey works fine, could be light grey/silver instead though
Newcastle - Parramatta, Titans, Warriors, Roosters, Cowboys
- a red away jersey would make more sense tbh
North Qld - Roosters, Knights, Warriors, Titans, Eels, Storm to a lesser extent Penrith and Tigers
- grey away jersey would make sense, current one is ridiculous
Parramatta - Newcastle, Warriors, Cowboys, Roosters, Storm
- ditch the white thing and wear the gold one
Penrith - Tigers, to a lesser extent Manly, Brisbane, Roosters, Storm, Cowboys
- pink works perfectly
St Geo Illa - Dogs barely
- red alternate is fine
Souths - Canberra
- they need a better alternate than the panel switch they currently do. Bring back the minties wrapper
Roosters - Cowboys, Storm, Warriors, Eels, to a lesser extent Titans, Knights
- current away jersey is fine
Warriors - Just about everyone
Not even sure what the solution is here but just replacing the blue lower half on the home kit to create the away one isn't a solution, especially when paired with blue shorts.
Wests Tigers - Penrith mostly, also Manly, Brisbane, Cowboys, Roosters
- less black on the orange away jersey; having a third white alternative wouldn't hurt tbh
