Since I was working on your query anyway... in addition and to support what Leon has stated...
Fair Work Ombudsman
If you have a dispute regarding your final pay with your employer and are unable to resolve it... then you can contact the Fair Work Ombudsman and ask them to assist you to resolve the dispute.
Your Minimum Sick Leave Entitlements
The term ‘personal/carer’s leave’ effectively covers both sick leave and carer’s leave. The minimum entitlement to paid personal/carer’s leave for an employee (other than a casual employee) is 10 days per year. 5 years = 50 days or 10 weeks.
An employee’s entitlement to paid personal/carer’s leave accrues progressively during a year of service according to the number of ordinary hours worked, and accumulates from year to year.
Personal/carer’s leave continues to accrue when an employee takes a period of paid personal/carer’s leave or paid annual leave. Personal carer’s leave and compassionate leave will not accrue on unpaid leave unless it is community service leave or it is provided for in an award or agreement.
Payslip figures are not final
The figure on your final pay slip is not legally binding, and can be challenged.
Was your termination fair? or unfair? If unfair - you have 21 days from your last day... to lodge an application with the Fair Work Commission.
Are you entitled to.. and were you paid redundancy pay? To determine this, we need to know whether your position will be filled by someone else, or your employer is downsizing the business... Also relevant is knowing how many employees work for your employer?
How much notice (if any) were you given regarding your termination? What does your employment contract (if any) say regarding notice?
