The codes share an oval ball, backward passing and the objective of grounding the ball in the in-goal, but they create very different rhythms. League repeatedly resets the defensive line; union allows longer contests for possession after a tackle.
Australian viewers often encounter both codes, so names can cause confusion. The NRL plays rugby league. Super Rugby and the Wallabies play rugby union.

How possession changes the tactics
League teams know they have a limited set before turning the ball over, so early tackles often build field position and the final tackle frequently ends with a kick. Union teams can retain the ball through many phases, but every ruck creates a contest and a risk of penalty or turnover.
The extra union players include two flankers, contributing to denser breakdowns. League's 13-player field creates more space and repeated one-on-one defensive decisions.
Substitutions and competition variations
International rugby league laws provide a named replacement and interchange framework, while NRL and NRLW conditions can add competition-specific settings. Rugby union distinguishes tactical substitutions from injury-related replacements and has specialist front-row requirements. Always use the current competition rules for bench management.
