Ever found yourself screaming at the TV, absolutely certain that try was clean—only for the video bunker to rule it out? Or worse, sitting at the ground on a Friday night, watching the big screen replay a call from five different angles, and still having no clue what's going on?
You're not alone.
The video bunker system has been part of the game for years, but for plenty of fans—especially those newer to the sport—it can feel like a mysterious black box where decisions get made by someone who clearly doesn't support your team.
Let's break down how the video bunker actually works, why those frustrating calls happen, and what you can do to understand—or at least predict—the outcome next time your star player dives for the corner.
Problem 1: Trying to Figure Out What the Bunker Can Actually Review
Symptoms: You see a try scored, the on-field referee points to the spot, but then the bunker intervenes. You're left wondering: Wait, can they just review anything?
Causes: The bunker protocols aren't always clearly communicated during broadcasts. Plus, the rules have changed over the years about what the bunker can look at and when.
Solution: Here's the current system in plain English.
The video bunker can review:
- All tries automatically (every single one, from every angle)
- Potential foul play (high tackles, dangerous contact, etc.) at any time during the game
- Disputed decisions referred by the on-field referee
- Forward passes (unless it's part of a try-scoring review)
- Strip calls
- Most ruck infringements
Problem 2: Understanding "No Clear Evidence" vs. "Insufficient Evidence"
Symptoms: One week, a try is awarded because there's "no clear evidence" to overturn it. The next week, a similar-looking try is disallowed for "insufficient evidence." You're confused about the difference.
Causes: These two phrases sound similar but mean opposite things in bunker language. The league doesn't always explain this distinction well.
Solution: Here's the cheat sheet.
"No clear evidence" = The bunker has looked at the footage and cannot see anything definitive that proves the on-field decision was wrong. The original call stands.
"Insufficient evidence" = The bunker cannot see enough to make a decision either way. In this case, the on-field decision also stands—but if the on-field ref was unsure and sent it up as a "try or no try," the bunker will make the call based on what they can see.
The practical takeaway for fans: if the on-field ref puts his hand up and says "try," the bunker needs clear, definitive footage to overturn it. If the ref says "no try," they need the same standard to award it. The difference is subtle, but it explains why some calls seem inconsistent.

Problem 3: The Bunker Takes Forever—What's Actually Happening?
Symptoms: You're sitting at the ground, the crowd is getting restless, and the bunker is taking what feels like five minutes. The bloke next to you is already onto his second pie.
Causes: The bunker isn't just watching one angle. They're reviewing multiple camera feeds simultaneously, checking for any possible infringement in the lead-up, and consulting with the on-field referee.
Solution: Here's what's happening during that delay.
- Angle selection: The bunker operator cycles through available camera angles (there can be many at professional games)
- Lead-up check: They review the previous tackle or phase for any foul play
- Try-scoring action: They check the actual grounding, any foot in touch, and any obstruction
- Communication: They speak with the on-field referee to clarify what the ref saw
Problem 4: When the Bunker Overrules the On-Field Referee
Symptoms: The ref is right there, pointing at the spot, clearly confident it's a try. Then the bunker says no. You're furious because "the ref was right there!"
Causes: The on-field referee makes a decision based on what they saw in real-time. The bunker has the benefit of slow-motion replay and multiple angles. Sometimes, the ref gets it wrong—and the bunker is there to correct it.
Solution: Understand the hierarchy.
The bunker always has the final say on tries and foul play. That's the whole point of the system. The on-field referee's job is to make the initial call, but if the bunker sees something different, the bunker's decision overrides.
For fans, this is particularly relevant when a player is chasing a kick into the in-goal. From the stands, it looks like he grounded it clean. The ref agrees. But the bunker might spot a millimeter of his boot dragging the sideline, or the ball moving slightly as he puts it down. The ref couldn't possibly see that from 20 metres away.
Problem 5: Bunker Decisions on Obstruction—What Counts?
Symptoms: A player runs a decoy line, accidentally bumps a defender, and suddenly a perfectly good try is disallowed. You're convinced it's a rubbish call.
Causes: Obstruction rules are complex. The bunker looks at whether the defending player was genuinely affected by the obstruction, not just whether contact occurred.
Solution: Here's what the bunker actually checks for obstruction.
They ask three questions:
- Did contact occur between an attacking player (without the ball) and a defender?
- Was that contact deliberate or accidental?
- Did the contact materially affect the defender's ability to make a tackle?
This is one of the most debated areas of bunker decision-making, and even experienced commentators sometimes get it wrong. The key is whether the defender was genuinely disadvantaged, not just touched.

Problem 6: The Bunker and the "Benefit of the Doubt"
Symptoms: The bunker announces "benefit of the doubt to the attacking team" and awards a try. Next week, the same scenario goes the other way. You're pulling your hair out.
Causes: The "benefit of the doubt" principle has been inconsistently applied over the years, and the league has adjusted its interpretation multiple times.
Solution: The current protocol is straightforward.
The benefit of the doubt only applies when:
- The on-field referee has awarded a try
- The bunker cannot find clear evidence to overturn it
If the on-field referee says "no try" or "unsure," there is no benefit of the doubt. The bunker must find clear evidence to award the try, or it stays as no try.
For fans watching a player chase a bomb: if the ref calls "try" and the bunker can't see anything definitive, the attacking team gets the four points. If the ref calls "no try," the bunker needs to see clear grounding to change it.
Problem 7: The Bunker Misses Obvious Foul Play
Symptoms: A high tackle happens right in front of you at the ground, but the bunker doesn't intervene. You're convinced the system is broken.
Causes: The bunker cannot review everything in real-time. They rely on:
- The on-field referee referring incidents
- The touch judges flagging issues
- The bunker operator spotting something while reviewing tries
The bunker is not watching every single tackle live. They're primarily focused on try-scoring reviews. For foul play to be reviewed, it usually needs to be:
- Flagged by the on-field officials
- Serious enough to warrant a "captain's challenge" (if available)
- Spotted incidentally during a try review
Prevention Tips: How to Avoid Bunker Frustration
- Watch the replays: At the ground, keep an eye on the big screen. The bunker's decision is usually based on something the broadcast cameras caught.
- Learn the refs: Different referees have different tendencies. Some send everything to the bunker; others make more on-field decisions. Knowing who's officiating helps predict outcomes.
- Understand the lead-up: Most disallowed tries come from something that happened before the ball went to the try-scorer. Watch for obstruction, knock-ons, or forward passes in the build-up.
- Check official reviews: The league publishes regular breakdowns of bunker decisions. Reading these helps you understand the current interpretation.
- Don't rely on crowd noise: The crowd reacts emotionally, not logically. Just because thousands of people are booing doesn't mean the bunker got it wrong.
When to Seek Official Guidance
If you're genuinely confused about a specific bunker decision, here's where to go:
- Official league website: They publish regular bunker reviews with explanations
- Rules page: The official rulebook is available online
- Club channels: Your club's official social media often explains contentious calls
- Match review committee findings: These are published regularly and explain why certain incidents were penalized or not
The Bottom Line
The video bunker isn't perfect—no system run by humans ever is. But understanding how it works takes away some of the frustration.
Next time you're at the ground watching your team, and the bunker takes an eternity to rule on a try, you'll know exactly what they're looking for. And when the call goes against us—well, you can still boo. That's part of the fun.
