Categories of crime and strict liability offences in Queensland: QCE Legal Studies
“The categories of crime in Queensland, including offences against the person, against property, against the state, drug, traffic, public order, and the special category of strict liability offences”
Queensland criminal offences fall into seven main categories: against the person, against property, against the state, drug, traffic, public order, preliminary and regulatory. Most are codified in the Criminal Code Act 1899 (Qld); drug offences are in the Drugs Misuse Act 1986 (Qld). Strict liability is a special category in which the prosecution need only prove the actus reus, justified by public protection and regulatory efficiency.

What this dot point is asking
QCAA wants you to know the main categories of crime in Queensland, where each is located in the statute books, and the special status of strict liability offences. Expect a 3-5 mark short response.
The answer
Categories of crime in Queensland
- 1. Offences against the person
- Crimes that cause harm or threat to a person. Includes murder (Criminal Code 1899 (Qld) s 302), manslaughter (s 303), assault (s 245), grievous bodily harm (s 320), and rape (s 349). The Criminal Code (Domestic Violence) and Other Legislation Amendment Act 2023 (Qld) inserted a coercive control offence which is scheduled to commence in 2025.
- 2. Offences against property
- Crimes that interfere with another's property. Includes stealing (Criminal Code 1899 (Qld) s 391), robbery (s 409), burglary (s 419), and arson (s 461).
- 3. Offences against the state
- Crimes that threaten state authority or integrity. Includes treason (Criminal Code 1899 (Qld) s 37) and offences against the Criminal Code Act 1995 (Cth) Divisions 80-82 (treason, urging violence, advocating terrorism).
- 4. Drug offences
- Possession, supply, production and trafficking of dangerous drugs. Governed by the Drugs Misuse Act 1986 (Qld). Examples: possession (s 9), supply (s 6), production (s 8), trafficking (s 5).
- 5. Traffic offences
- Driving offences regulated under the Transport Operations (Road Use Management) Act 1995 (Qld). Examples: drink driving (s 79), unlicensed driving, dangerous operation of a vehicle (Criminal Code 1899 (Qld) s 328A).
- 6. Public order offences
- Conduct that disturbs the peace. Examples: public nuisance (Summary Offences Act 2005 (Qld) s 6), obstructing a police officer (Police Powers and Responsibilities Act 2000 (Qld) s 790), affray (Criminal Code 1899 (Qld) s 72).
- 7. Preliminary (inchoate) offences
- Attempt (Criminal Code 1899 (Qld) s 535), conspiracy (s 541), and incitement.
- 8. Regulatory offences
- Breaches of regulatory regimes including work health and safety (Work Health and Safety Act 2011 (Qld)), environment (Environmental Protection Act 1994 (Qld)) and consumer protection.
Strict liability offences
A strict liability offence is one where the prosecution does not need to prove a mental element (mens rea) for the prohibited conduct. Proof of the actus reus is sufficient.
Common examples in Queensland:
- speeding offences under the Transport Operations (Road Use Management) Act 1995 (Qld);
- many offences under the Summary Offences Act 2005 (Qld);
- regulatory offences under the Work Health and Safety Act 2011 (Qld) and the Environmental Protection Act 1994 (Qld).
Strict liability is justified by three considerations:
- public protection (especially in road safety and environmental regulation);
- regulatory efficiency (the volume of traffic and minor regulatory offences would be unworkable if mens rea had to be proved each time);
- relatively low penalties.
The leading authority on whether a statute creates a strict liability offence is He Kaw Teh v The Queen (1985) 157 CLR 523, which held that the presumption of mens rea can be displaced only by clear statutory words or by necessary implication.
The mistake of fact defence
In Queensland, the Criminal Code 1899 (Qld) s 24 provides a defence of honest and reasonable mistake of fact. Importantly, the defence may apply even to some offences that would otherwise be treated as strict liability under the common law: the High Court in CTM v The Queen (2008) 236 CLR 440 held that the s 24 defence applies to a charge of unlawful carnal knowledge unless expressly excluded by the relevant statute.
Why categorisation matters
- it shapes the sentencing range (offences against the person attract higher maxima than property offences);
- it determines the court of trial (indictable matters tried on indictment in the District or Supreme Court of Queensland; summary matters in the Magistrates Court of Queensland);
- it identifies the statute that defines the offence (Criminal Code, Drugs Misuse Act, etc.);
- it informs the mens rea requirement (strict liability vs full mens rea).
A common Unit 1 task gives a scenario and asks you to classify the offence and explain the consequences. Work through it in steps.
Step 1: Identify the category
Decide whether the conduct is against the person, against property, against the state, a drug, traffic, public order, preliminary or regulatory offence.
Step 2: Locate the governing statute and section
Cite the relevant Act and section (Criminal Code Act 1899 (Qld), Drugs Misuse Act 1986 (Qld), and so on).
Step 3: State the mens rea position
Decide whether full mens rea is required or whether the offence is strict liability.
Step 4: Identify the court and sentencing range
Note whether the matter is indictable (District or Supreme Court) or summary (Magistrates Court), and the sentencing implication of the category.
Step 5: Apply to the scenario
Conclude by applying the classification to the facts and its consequences.
- Naming categories without the statute
- QCAA rewards matching each category to its governing Act and section. Pair every category with authority.
- Assuming strict liability removes all defences
- The s 24 mistake of fact defence can still apply to some strict liability offences (CTM v The Queen).
- Confusing category with seriousness
- Indictable versus summary classification, not the category label alone, determines the court of trial.
- Ignoring the consequences of categorisation
- Categorisation shapes the statute, the court, the sentencing range and the mens rea requirement; state why it matters.

Practice7 marksAnalyse the justifications for strict liability offences and evaluate whether the mistake of fact defence provides an adequate safeguard. Refer to authority.Show worked answer →
A QCAA Paper 1 analyse and evaluate response needs the justifications, the s 24 safeguard and a judgement.
- Justifications
- Public protection (road safety, environment), regulatory efficiency given the volume of minor offences, and relatively low penalties.
- The s 24 safeguard
- The Criminal Code Act 1899 (Qld) s 24 mistake of fact defence can apply even to some offences treated as strict liability at common law (CTM v The Queen (2008) 236 CLR 440), unless expressly excluded.
- Authority on classification
- He Kaw Teh v The Queen (1985) 157 CLR 523 displaces the presumption of mens rea only by clear words or necessary implication.
- Judgement
- Conclude whether s 24 adequately balances efficiency against fairness. Markers reward authority and a reasoned verdict.
