I completely understand your frustration - this situation is both legally problematic and professionally unfair. You're absolutely right to feel disheartened, and you have strong grounds to challenge this discriminatory treatment. Let me look up the most relevant information about your rights in this situation.

You're facing a frustrating situation that combines both workplace discrimination concerns and strategic career advancement challenges. Let me break down your legal position and practical options.

Legal Protections Under Australian Law

The Fair Work Act provides strong protections against unlawful workplace discrimination when an employer takes adverse action against an employee because of protected attributes including age. Your situation potentially involves discriminatory treatment based on when you started and your employment pathway rather than your actual performance or capabilities.

Under the Fair Work Act, the Fair Work Commission can make equal remuneration orders requiring employees receive equal remuneration for work of equal or comparable value, and once made, these orders will overrule enterprise agreements if they leave affected employees better off overall.

The key legal question is whether you're performing work of equal or comparable value to the graduate program participants while receiving systematically different remuneration due to an arbitrary classification system rather than merit-based factors.

Strategic Approach to Address This Issue

1. Document Everything Immediately

• Record the March promise from your team leader about the band increase
• Document the arbitrary equipment knowledge reason given for reneging
• Keep records of your work outputs, achievements, and responsibilities
• Note specific examples where your work equals or exceeds what graduate program participants do
• Save any communications about performance expectations or achievements

2. Research Your Position Thoroughly

• Obtain a copy of your Enterprise Bargaining Agreement and review the salary band progression criteria
• Request clarity on what specific metrics determine band increases (this should be transparent)
• Document the graduate program salary increase structure (6% and 8% increases)
• Compare your job duties with those of graduate program participants

3. Build Your Business Case

Frame this as equal pay for equal work rather than challenging your team leader's authority:

• "I'm seeking clarity on how our remuneration system ensures equal pay for equal work"
• "I want to understand the pathway for career progression outside the formal graduate program"
• "I'm concerned about potential pay equity issues given I'm performing comparable work to graduate program participants"

4. Strategic Communication Approach

Given your team leader's resistance to being challenged, approach this diplomatically:

With HR First: Schedule a meeting to discuss "career progression pathways and pay equity" rather than framing it as a complaint about your team leader.

Key Points to Raise:

• You're performing equivalent work to graduate program participants
• The salary progression system appears to create unequal remuneration for equal work
• You're seeking transparent criteria for advancement outside the graduate program
• You want to ensure the company's practices align with fair work principles

With Your Team Leader: After speaking with HR, approach as seeking mentorship:

• "I'd like to understand the specific competencies needed for advancement"
• "Can we establish clear, measurable goals for the next review period?"
• "I want to ensure I'm developing the right skills for career progression"

Escalation Options

If internal discussions don't resolve this:

Fair Work Commission Application

An application for an equal remuneration order can be made by an affected employee, a union representing an employee, or the Sex Discrimination Commissioner. You can use Form F46A to apply for an equal remuneration order if you believe you're not receiving equal remuneration for work of equal or comparable value.

Union Support

If your workplace has union representation, they can provide strategic advice and potentially support an equal remuneration application on your behalf.

Fair Work Ombudsman

They can investigate potential discrimination and provide guidance on whether your situation constitutes adverse action based on arbitrary classification rather than merit.

Timeline Strategy

Immediate (Next 2 weeks):

• Document everything thoroughly
• Schedule HR meeting about "career progression pathways"
• Review your EBA for advancement criteria

Short-term (Next month):

• Follow up HR meeting with written summary
• Request written criteria for band advancement
• Have structured conversation with team leader about development goals

Medium-term (2-3 months):

• If no progress, consider formal complaint or Fair Work Commission application
• Remember that equal remuneration orders can only operate from when they're made forward, not retrospectively

Legal Context

Employers who contravene equal remuneration orders face significant penalties, and from January 2025, intentional underpayment of wages is a criminal offence. This gives you strong leverage in discussions.

Your situation appears to involve systematic pay inequality based on employment pathway rather than work value or performance. This is exactly the type of issue Australian employment law is designed to address. Approach this strategically, document everything, and don't let your team leader's communication style prevent you from advocating for fair treatment.

The upcoming graduate hire actually strengthens your position - it will create a direct comparison showing unequal pay for equal work within the same team. Use this timing to your advantage in discussions with HR and management.
