If the Australian Securities and Investments Commission (ASIC) has contacted you about an insider trading investigation in NSW, or you suspect you may have acted on information you shouldn’t have, you need to understand both the seriousness of the situation and your options.
Illegal insider trading is one of Australia’s most serious corporate criminal offences. Individuals currently face up to 15 years imprisonment and fines reaching $1.575 million. ASIC uses real-time surveillance technology to identify suspicious trading patterns, often within days of the trades occurring.
What surprises many people is just how widely these laws reach. You don’t need to be a company director or stockbroker to be caught up in an insider trading investigation. Family members, friends, legal professionals, and anyone who receives and acts on a confidential “tip” can all face prosecution.
This fact sheet explains what insider trading actually involves, who can be charged, how ASIC investigates, what the penalties are, and what defences may be available to you.

What is Insider Trading?
Insider trading occurs when a person in possession of material, non-public information about a company trades in that company’s securities, or tips off someone else who then trades.
The offence is set out in sections 1042A to 1043L of the Corporations Act 2001 (Cth). To establish the offence, ASIC must prove all of the following:
- You possessed information about a company or financial product
- That information was not generally available to the public
- The information was material, meaning it would have a material effect on a reasonable person’s decision to buy or sell
- You knew, or ought to have known, the information was inside information
- You traded in securities, directed someone else to trade, or communicated the information to another person knowing they would likely trade on it
Common examples of price-sensitive information include: confidential merger negotiations, upcoming profit warnings, major contract wins or losses, CEO resignations, pending regulatory decisions, and planned capital raisings.
What Counts as “Inside Information”?
Not Generally Available
Information is considered “not generally available” unless it is publicly available information, for example, via an ASX announcement or media release, and a reasonable period has passed for the market to absorb it.
The test is not whether a sophisticated analyst could piece it together from public sources; it’s whether the average investor has access to it.
Material Information
Information is material if it would be likely to influence a reasonable investor’s decision to buy or sell stocks. This is a broad standard. It includes:
- Mergers and acquisitions in negotiation
- Unannounced financial results or profit warnings
- Major contract wins or losses
- Regulatory approvals or licence revocations
- Board or executive changes not yet announced
- Significant litigation outcomes or settlements
- Plans for share placements or debt refinancing
Who Can Be Charged?
Insider trading laws apply far more broadly than most people realise.
Primary insiders, those closest to the information, include company directors, officers and employees, lawyers and accountants advising on transactions, investment bankers, auditors, and government officials with regulatory knowledge.
Secondary recipients (“tippees”) can also be charged. This includes anyone who receives sensitive information, whether at a dinner conversation, in a casual phone call, or in a business meeting, and then trades on it to gain an advantage, or passes it on. You can be charged even if you are several steps removed from the original source, provided you knew or should have known the information was confidential and price-sensitive.
Penalties
| Offence | Who | Maximum Penalty |
| Insider trading (trading or procuring trade) | Individual | 15 years imprisonment and/or $1.575M fine |
| Insider trading | Corporation | Greater of $15.75M, 3x profit, or 10% of annual turnover |
| Tipping (communicating inside information) | Individual | 15 years imprisonment and/or $1.575M fine |
| Civil penalty (alternative to prosecution) | Individual | Up to $1.575M |
ASIC can also apply for court orders requiring disgorgement of any benefit derived from the trading, including any loss avoided. Even where no direct financial gain was made, civil penalties can still be career-ending.
How ASIC Detects Insider Trading in NSW
ASIC’s Market Integrity team monitors trading across the ASX continuously, using sophisticated surveillance systems to flag unusual activity.
ASIC’s detection tools include:
- Real-time algorithms that identify unusual trading volume or price movements
- Automated detection of suspicious trades in the period immediately before a company announcement
- Pattern recognition systems that identify traders who consistently profit ahead of announcements
- Network analysis to map connections between traders and company insiders
Once suspicious activity is flagged, ASIC can obtain trader identities from brokers, access phone records, map relationships between traders and insiders, execute search warrants to seize computers and devices, and, critically compel individuals to attend examinations under oath. Refusing to cooperate with an ASIC examination is itself a separate offence.
Investigations often begin within days of a suspicious trade. By the time ASIC makes contact, they typically understand the extent of the trading activity and have a substantial body of evidence already assembled.
Real-World Scenarios
Scenario 1: The Merger Tip
A lawyer at a firm working on a confidential acquisition tells their spouse that the target company is about to be taken over at a significant premium. The spouse purchases shares the next morning. Both the lawyer (as the tipper) and the spouse (as the tippee who traded) may face insider trading charges, even if no money changed hands between them.
Scenario 2: The Employee Who Trades Ahead of Results
A senior finance manager at an ASX-listed company knows that the company’s half-year results, due to be announced in two weeks, will significantly miss expected analyst forecasts. She sells her shareholding before the announcement, avoiding the loss that followed. This is a textbook insider trading case.
Scenario 3: The Overheard Conversation
A contractor working on-site at a company’s head office overhears a meeting about an imminent regulatory approval that will dramatically boost the company’s share price and investor interest. He buys shares that afternoon. The fact that he was not an employee and did not receive a direct tip does not necessarily protect him if he knew or should have known the information was confidential and price-sensitive.
Defences to Insider Trading
Facing an ASIC investigation does not automatically mean a conviction is inevitable. Several defences may be available, depending on the specific facts.
1. No knowledge the information was inside information
If you can demonstrate that you genuinely did not know, and had no reasonable grounds to suspect the possibility, that the information was inside information, this can amount to a full defence if accepted by the court. This requires showing the source gave no indication of confidentiality, and that you had no reason to believe the information was price-sensitive.
2. The information was not material
If the information would not, in fact, have materially affected the value of the shares, it does not qualify as inside information. This defence typically requires expert evidence from a financial analyst or economist.
3. The information was already generally available
If the information was already public at the time you traded, through an ASX announcement, media coverage, or information readily deducible from public sources, there is no offence.
4. Pre-existing trading plans or instructions
If your trades were made pursuant to a trading plan or standing instruction that was put in place before you received the inside information, this can lead to a viable defence. Courts will take into account the timing of the trading plan relative to when you received the information.
Frequently Asked Questions
What is “inside information” in the context of insider trading?
Inside information is non-public, material information about a company that, if publicly known, would likely affect the company’s share price. Examples include confidential takeover negotiations, unannounced profit results, major contract decisions, regulatory approvals, and executive changes not yet made public.
Can I be charged if I didn’t personally profit?
Yes. “Tipping”, passing inside information to someone else who then trades, carries the same maximum penalty as insider trading itself: 15 years imprisonment and a $1.575 million fine. Your personal profit or loss is irrelevant to the question of guilt.
How does ASIC detect insider trading?
ASIC uses real-time algorithmic surveillance of ASX trading to flag unusual activity, particularly in the period before company announcements. Once flagged, ASIC can identify traders via their brokers, obtain phone records, map connections to insiders, and compel individuals to attend examinations under oath. Most investigations begin with automated pattern detection.
Do I have to answer ASIC’s questions?
ASIC has broad compulsory examination powers under the Australian Securities and Investments Commission Act 2001 (Cth). You can be required to attend and give evidence under oath. Refusing to comply is a criminal offence. However, you have the right to legal representation before and during any examination, and you should exercise that right before making any contact with ASIC.
What are the defences to insider trading?
The main defences are: you did not know the information was inside information; the information was not material; the information was already public when you traded; or you traded pursuant to a pre-existing trading plan created before receiving the information. Each defence requires strong supporting evidence and careful legal preparation.
Can ASIC pursue civil penalties instead of criminal prosecution?
Yes. ASIC has the option of pursuing civil penalty proceedings as an alternative to criminal prosecution through the Commonwealth Director of Public Prosecutions. Civil proceedings have a lower standard of proof and can still result in substantial fines, banning orders, and disgorgement of profits. Experienced legal representation can sometimes assist in achieving a civil rather than criminal resolution.
Practical Steps If You Are Under Investigation for Insider Trading
If ASIC contacts you:
- Do not make any voluntary statements before speaking to a lawyer
- Do not delete or alter any documents, emails, or trading records
- Preserve all relevant communications, including phone records and emails
- Contact an experienced criminal defence or ASIC defence lawyer immediately
What your lawyer will do:
- Address the specific allegations and review ASIC’s evidence
- Advise you on your obligations during any compulsory examination
- Assess available defences based on the facts
- Negotiate with ASIC where appropriate to seek civil rather than criminal resolution
- Represent you in court if charges are laid
Why Early Legal Advice Matters in Insider Trading Cases
Insider trading investigations are factually and legally complex. They involve detailed financial analysis, telecommunications evidence, and sophisticated surveillance data gathered over months. By the time ASIC makes contact, they often have a comprehensive picture already assembled.
Getting expert legal advice early, before you respond to ASIC, before you attend any examination, before you say anything, can significantly affect the outcome. The wrong response at the examination stage, or inadvertent cooperation that damages your position, can be very difficult to undo.
