A simple, structured system designed to support early communication and reduce psychosocial risk before issues escalate in high-risk work environments.
Designed for mining, construction, and other high-risk industries, Green Thumb integrates into existing systems without disruption.
What Is Green Thumb
Green Thumb is a simple, visible system designed to identify early signs of psychosocial risk in high-risk work environments.
It enables individuals to signal when support is needed before issues escalate into safety, behavioural, or performance-related risks.
The system operates within existing Work Health and Safety (WHS) frameworks and supports early intervention without adding complexity to current processes.
How It Works
Green Thumb provides a structured way for individuals to communicate early.
A visible marker indicates the need for a check-in, while the individual remains engaged and accountable in their role. Teams are then able to respond within clearly defined expectations.
This creates a consistent approach to communication and reduces the need for reactive responses after issues have already escalated.
Workplace Safety
Green Thumb can also be used as an early fatigue indicator, particularly during mid to late shift periods when extended work hours begin to affect performance.
Simple, accessible markers are available on site, enabling workers to signal when they need support. This allows teams to respond early and helps maintain safe, consistent, and high-performing operations.
Green Thumb offers a low-stigma way for individuals to communicate a simple message:
“I’m still good to work — I could just use a bit of extra support.”
This signal does not remove responsibility. Instead, it creates early awareness and allows for a structured response.
Markers may be made available in crib rooms, tool stores, or other designated areas on site. They are applied by the individual when additional support is needed, while full engagement with tasks and responsibilities is maintained.
The signal alerts team members or supervisors to check in and enables an early response without disrupting operations.
When a Green Thumb signal is identified, a short check-in is completed. Tasks may be adjusted where required, and additional supervision or support can be applied. Work continues within safe and controlled conditions.

Why It Matters
In high-risk environments, many issues are only addressed once they’ve already become visible.
Fatigue can impact performance.
Disengagement can reduce awareness.
Behavioural changes can increase workplace risk.
Green Thumb supports earlier identification and response — helping reduce escalation and improve consistency across teams.
Industry Alignment
Green Thumb aligns with existing WHS frameworks and site systems. It does not replace current processes — it strengthens them.
Supports psychosocial risk management
Reinforces safety culture
Integrates into daily operations
Requires no major structural change
Partner With Green Thumb
Green Thumb is seeking partners across mining, construction, transport, and industrial operations.
Partnership opportunities may include pilot implementation, workforce rollout, training and communication development, and strategic sponsorship.
Green Thumb supports early-stage workforce safety innovation, practical system-based risk reduction, and measurable workplace and community outcomes.
Developed Through AMHTO
Green Thumb is an independently adoptable system developed as part of the AMHTO model.
AMHTO applies structured, upstream approaches to workforce development and psychosocial risk. Green Thumb represents the early-stage engagement component of that model.
