Have you left or are you leaving your current employment? If so, you are likely thinking about your future and the next opportunity, but before you move on, you must consider your legal obligations around the information you take with you.
Confidentiality obligations don’t end the day your job does. They continue to shape what you can and cannot do with the information you acquired during your employment whether that’s a client list, an internal process, or even the pricing strategy you helped to design. The scope of these duties depends on where the information came from, how secret it really is, and whether it has become part of your own general knowledge and experience.
The sources of your obligation
The duty of confidentiality in employment arises from several overlapping sources: contract, common law and statute.
Most employment contracts contain an express confidentiality clause prohibiting the disclosure or use of sensitive information except as required for your role. Even if such a clause is missing, the common law imposes an equitable obligation on employees not to misuse information obtained in circumstances of confidence. Statute or legislation adds another layer. In the Corporations Act 2001 (Cth):
- Section 182 states that you cannot use your former position to gain an unfair advantage to yourself or cause harm to your previous employer.
- Section 183 states that you must not use information obtained during your employment to benefit yourself or a third party, or to cause damage to your former employer. This obligation extends beyond your employment.
With that said, the courts recognise the tension between an employer’s legitimate interest in protecting its’ business and an employee’s right to use their own skills, experience, and ‘stock of knowledge’ gained through employment. The court has adopted a ‘balancing’ approach, treating confidentiality as a matter of degree and context, focusing on whether disclosure would cause harm to the employer and whether restraining its use would unfairly prevent the former employee from working in their chosen field.
Your obligations post-employment
If your employment contract clearly defines ‘confidential information’ and specifies that the obligation survives termination, those terms will govern the scope of your duties. However, if, no express clause exists, only a limited duty is implied. This means, after the employment relationship has ended, the law will not prevent you from using information that has become part of your professional skill set. What remains protected are the employer’s genuine trade secrets – things that are still secret, commercially valuable, and identifiable as belonging to the employer rather than to you.
Courts therefore distinguish between discrete, protectable information and general know-how. The dividing line often turns on whether restraining use would effectively prevent you from working in your field.
What counts as confidential information
In the absence of a contractually defined term, there is no fixed legal definition of ‘confidential information’. In Australian Medic-Care Company Pty Ltd v Hamilton Pharmaceutical Pty Ltd, the court used the following questions to determine whether information was confidential to a business:
- Is the information widely known within the industry?
- Could it be discovered independently through reverse engineering or experimentation?
- Did the employer invest time or money in producing it?
- What steps were taken to preserve its secrecy? For example, was it password protected? and
- Would a reasonable person consider the information to be the property of the employer?
Information that fails these tests, for example, industry-standard practices or knowledge that forms part of your own professional experience, will rarely be treated as confidential once you move on, however, information that gives you a ‘head start’ might.
The Springboard doctrine
Even if information could eventually be discovered by lawful means, courts may prevent its use if it gives a departing employee an unfair head start. This principle, known as the ‘springboard doctrine’, stops former employees from exploiting an advantage obtained through their employment to accelerate competition:
- If the information was imparted in circumstances of trust;
- Remains confidential; and
- Is being used or threatened to be used without authority.
In such circumstances, courts have repeatedly granted injunctions where employees have misused this kind of information, recognising that even temporary misuse can distort fair competition.
Consequences of breach
When confidentiality obligations are breached, courts have broad powers to intervene. They can issue injunctions to stop you from using or disclosing the information, require you to deliver up or destroy confidential material, and order payment of damages or an account of profits representing any advantage gained. These remedies are in addition to potential disciplinary action and reputational harm. Courts are particularly unforgiving where the misuse was deliberate or where the employee took documents or data in tangible form before leaving.
Managing your transition
Before leaving a role, review your employment contract carefully and return or permanently delete all company information in your possession. If data is stored on personal devices or cloud accounts, ensure that it is removed securely. Many employees provide written confirmation to their employer that this has been done. Avoid using company templates, pricing information, or client lists in your new position – even if you helped to create them. If you are uncertain about what falls within your continuing obligations, obtain legal advice before starting a competing role.

A careful balance
During employment, the duty of confidentiality is absolute. After employment, it narrows but does not disappear. Courts will restrain the misuse of genuine trade secrets or confidential material but will not stop you from using the general knowledge and expertise that form part of your professional identity. Modern employment is increasingly ‘knowledge-based’ – employees often generate the very information they are later told they cannot use. The law is gradually adapting to this reality, seeking a fair balance between protecting business interests and allowing people to pursue their careers freely.
Understanding where that boundary lies – between what you know and what your employer owns – is the key to protecting your reputation and your next opportunity.
