Introduction
A landmark Monash University study, published in PLOS One in January 2026, has quantified what many in the LGBTQ+ community have long known: structural barriers in Australia’s labour market remain deeply entrenched. Analysing data from more than 14,000 Australians across the HILDA Survey waves 20 and 23, researchers found that gay and lesbian adults are more than twice as likely to be unemployed as their heterosexual peers. This disparity persists even when accounting for age, education, and socioeconomic background—pointing not to individual failings but to systemic workplace-level barriers. Perhaps most tellingly, the study reveals severe underrepresentation of LGBTQ+ individuals in trades, manual occupations, manufacturing, and construction—sectors that form the backbone of Australia’s economy. This is not a problem of who gets hired; it is a problem of who never applies, who leaves, and who looks at an entire industry and decides it is not for people like them.
Learning Objectives
- Understand the quantitative evidence of LGBTQ+ employment disparities from the HILDA Survey and Monash University research
- Identify structural and cultural barriers in male-dominated industries that lead to anticipatory avoidance and occupational segregation
- Learn how to leverage data science, DEI analytics, and practical workplace interventions to measure and mitigate bias
- The Data Doesn’t Lie: Breaking Down the HILDA Survey Findings
The Household, Income and Labour Dynamics in Australia (HILDA) Survey is a nationally representative longitudinal study that tracks the same individuals over time. Sexual identity data were collected in wave 20 (2020) from 14,302 participants, and gender identity data in wave 23 (2023) from 13,981 participants. This robust dataset allowed researchers to examine both cross-sectional and longitudinal patterns of work participation.
The numbers are stark. Gay and lesbian participants were more than twice as likely to be unemployed compared to heterosexual Australians (prevalence ratio 2.05, 95% CI 1.01–4.14). They were also significantly less likely to work in trades or manual occupations (PR 0.55, 95% CI 0.36–0.85) or in manufacturing and construction (PR 0.40, 95% CI 0.23–0.72). Bisexual participants faced even broader challenges: higher unemployment (PR 2.05), greater labour force non-participation (PR 1.91), and a higher likelihood of transitioning out of employment over time (IRR 2.08). Transgender and gender diverse participants worked fewer hours on average and were significantly less likely to be employed in manufacturing, utilities, and construction (PR 0.35) compared to cisgender peers.
For the Data Analyst: To replicate similar analyses, you can access HILDA data via the Australian Data Archive. Below is a Python snippet using `pandas` and `statsmodels` to compute prevalence ratios for unemployment by sexual identity:
import pandas as pd
import statsmodels.formula.api as smf
Load HILDA data (hypothetical structure)
df = pd.read_csv('hilda_wave20.csv')
Poisson regression with robust variance for prevalence ratios
model = smf.poisson("unemployed ~ C(sexual_identity) + age + education + income",
data=df, exposure=df['population_weight']).fit()
print(model.summary())
- Anticipatory Avoidance: The Hidden Filter Before the Application
One of the study’s most important contributions is the concept of anticipatory avoidance—where LGBTQ+ individuals steer away from workplaces perceived as unsafe or unwelcoming. This is not irrational fear; it is a calculated response to lived experience and observable cultural cues. Cis male-dominated and culturally conservative sectors—construction, manufacturing, and mining—had particularly low representation of LGBTQ+ workers.
Lead author Dr Dee Tomic observed: “Many LGBTQ+ people may prioritise psychological safety over pay or career progression if workplace cultures feel hostile or exclusionary”. This results in occupational segregation that limits long-term economic security. The problem isn’t only who gets hired—it’s who never applies, who leaves, and who looks at an industry and decides it isn’t for people like them.
For the IT Professional: This pattern mirrors what we see in cybersecurity and tech—fields where bro culture, microaggressions, and lack of visible representation drive talented individuals away before they even submit a résumé. Consider auditing your job descriptions for gendered language using tools like Gender Decoder or Textio. Below is a PowerShell script to scan a directory of job description files for bias indicators:
PowerShell: Scan job descriptions for biased language
$biasWords = @("aggressive", "dominant", "ninja", "rockstar", "guru", "manpower")
$files = Get-ChildItem -Path ".\job_descriptions\" -Filter ".txt"
foreach ($file in $files) {
$content = Get-Content $file.FullName -Raw
foreach ($word in $biasWords) {
if ($content -match $word) {
Write-Host "BIAS DETECTED in $($file.Name): '$word' found" -ForegroundColor Yellow
}
}
}
- Structural vs. Individual: Why Education and Age Don’t Explain the Gap
A critical finding of the Monash study is that employment inequalities persist even after controlling for age, education, and socioeconomic background. This is the statistical smoking gun that rules out individual-level explanations (e.g., differences in qualifications or career choices) and points squarely at structural and workplace-level barriers.
In practical terms, this means a gay or lesbian Australian with the same CV, same degree, and same years of experience as a heterosexual peer still faces a significantly higher probability of unemployment and exclusion from entire industry sectors. The barriers are baked into hiring practices, workplace cultures, promotion pipelines, and even the informal networks through which trades apprenticeships and construction jobs are often secured.
For the Security Engineer: This is analogous to a vulnerability that persists across all patch levels—it’s not a configuration issue; it’s a design flaw. Just as we conduct threat modelling to identify systemic weaknesses in our infrastructure, organisations must conduct inclusion threat modelling to identify points in the employee lifecycle where bias enters. Consider implementing blind recruitment practices (removing names, gender indicators, and educational institutions from initial CV screenings) and using structured interviews with standardised scoring rubrics to reduce subjective bias.
- The Public Health Imperative: Employment as a Social Determinant
Dr Tomic warned that reduced access to secure work carries long-term consequences for financial security, mental health, and wellbeing. “These patterns are concerning not only from an equity perspective, but also for public health,” she said. “Employment is a major social determinant of health”.
This framing transforms the issue from a matter of fairness to one of population health. Unemployment and underemployment are linked to higher rates of depression, anxiety, substance abuse, and even suicide. When an entire community is systematically filtered out of stable, well-paid industries, the health impacts ripple across generations.
For the Cybersecurity Professional: Consider the parallel to human factors in security. Just as we recognise that employee wellbeing affects security posture (stressed employees are more likely to make errors or fall for phishing), we must recognise that exclusionary cultures create insider risk—not from malice, but from disengagement. Organisations with high levels of perceived inequity experience higher turnover, lower productivity, and greater security incidents. Below is a Linux command to analyse your organisation’s retention data by demographic group (assuming anonymised HR data in CSV format):
Linux: Analyse retention rates by demographic group
Assumes HR data with columns: employee_id, start_date, end_date, gender_identity, sexual_orientation
Load data and compute average tenure
awk -F',' 'NR>1 {tenure[$5]+=($4-$3); count[$5]++} END {for(g in tenure) print g, tenure[bash]/count[bash]}' hr_data.csv | sort -k2 -1
- Building Inclusive Digital Infrastructures: From Policy to Practice
The study underscores the need for inclusive workplace policies, stronger anti-discrimination measures, and better data collection on sexual and gender diversity in employment. Dr Tomic emphasised: “Improving LGBTQ+ inclusion at work isn’t just about individual workplaces. It requires broader cultural change, inclusive education and career pathways, and structural reforms that ensure everyone has access to safe, meaningful, and secure employment”.
For technology leaders, this means embedding inclusion into the digital infrastructure itself. Consider the following practical steps:
- Data Dashboards: Build real-time DEI dashboards that track representation, promotion rates, and retention by demographic group. Use tools like Power BI, Tableau, or open-source Superset.
- Anonymous Employee Surveys: Deploy regular, anonymous pulse surveys using platforms like Qualtrics or TinyPulse to measure psychological safety and belonging.
- Bias Audits: Conduct regular audits of your AI/ML systems—particularly those used in recruitment, performance evaluation, and promotion—to ensure they are not perpetuating bias. Use tools like IBM AI Fairness 360 or Google What-If Tool.
For the Cloud Architect: When designing cloud-1ative applications, consider how your identity and access management (IAM) policies might inadvertently exclude or misgender users. Ensure your systems support preferred names, pronouns, and multiple gender options in user profiles. Below is a Terraform snippet for deploying an inclusive IAM policy on AWS:
Terraform: Inclusive IAM policy with support for preferred identity attributes
resource "aws_cognito_user_pool" "inclusive_pool" {
name = "inclusive-user-pool"
schema {
name = "preferred_name"
attribute_data_type = "String"
mutable = true
required = false
}
schema {
name = "pronouns"
attribute_data_type = "String"
mutable = true
required = false
}
schema {
name = "gender_identity"
attribute_data_type = "String"
mutable = true
required = false
}
}
- The Business Case: Diversity as a Competitive Advantage
Beyond ethics and public health, there is a compelling business case for inclusion. Diverse teams are more innovative, make better decisions, and outperform homogeneous groups. In the tech sector—where talent is scarce and competition is fierce—excluding qualified LGBTQ+ individuals is not just unjust; it is commercially irrational.
The construction, manufacturing, and trades sectors are facing severe labour shortages. By failing to create welcoming environments, these industries are leaving billions of dollars of economic value on the table. The Monash study suggests that anticipatory avoidance is a significant driver of this exclusion—meaning that improving workplace culture could directly expand the talent pool.
For the IT Manager: Consider implementing mentorship and sponsorship programs specifically designed for underrepresented groups. Use Slack or Microsoft Teams to create safe, moderated channels for LGBTQ+ employees and allies. Below is a Python script to analyse your organisation’s promotion velocity by demographic group:
import pandas as pd
from scipy import stats
Load promotion data
df = pd.read_csv('promotions.csv')
Group by sexual orientation and calculate average time to promotion
grouped = df.groupby('sexual_orientation')['years_to_promotion'].mean()
print(grouped)
Perform t-test to check statistical significance
hetero = df[df['sexual_orientation'] == 'Heterosexual']['years_to_promotion']
lgbtq = df[df['sexual_orientation'] != 'Heterosexual']['years_to_promotion']
t_stat, p_value = stats.ttest_ind(hetero, lgbtq)
print(f"T-test p-value: {p_value}")
What Undercode Say
- Data is the first step, not the last. The Monash study provides irrefutable evidence of structural inequality. But data without action is just noise. Organisations must move from measurement to meaningful intervention.
-
Culture travels. As Storm Hassett observed, the culture you create today shapes who applies for the job tomorrow. This is not abstract—it is a direct call to action for every manager, team lead, and executive. Psychological safety is not a nice-to-have; it is a prerequisite for attracting and retaining top talent.
The findings from this study should serve as a wake-up call for every industry, but particularly for those in trades, manufacturing, and technology—sectors that pride themselves on innovation but have failed to innovate when it comes to inclusion. The structural barriers identified are not inevitable; they are the product of decades of cultural inertia, and they can be dismantled with intentional effort. The tools exist—from blind recruitment to inclusive IAM to DEI dashboards. What is lacking is the will to implement them at scale. As Dr Tomic noted, this requires broader cultural change, not just individual workplace policies. The question is whether Australian industries—and the tech sector that supports them—are ready to rise to the challenge.
Prediction
- +1 The growing availability of longitudinal data like HILDA will enable more sophisticated DEI analytics, allowing organisations to identify and address bias at every stage of the employee lifecycle. This will drive the development of new AI-powered tools for bias detection and mitigation.
-
-1 Without systemic intervention, the occupational segregation documented in this study will persist, widening the economic and health gaps between LGBTQ+ and heterosexual Australians. The cost—both human and financial—will be borne by individuals, communities, and the broader economy.
-
+1 The technology sector, with its data-driven culture and capacity for rapid change, is uniquely positioned to lead the way in inclusive workplace practices. Companies that embrace this opportunity will gain a competitive advantage in the war for talent.
-
-1 If the tech industry fails to address its own diversity gaps, it risks reproducing the same patterns of exclusion seen in trades and manufacturing—filtering out talented individuals before they even apply, and perpetuating a homogenous, less innovative workforce.
-
+1 The Monash study provides a evidence base for policy reform. Governments and industry bodies now have the data they need to implement targeted interventions—from apprenticeship outreach programs to anti-discrimination enforcement—that could dramatically improve outcomes within a single generation.
