- actus reus
- Related: mens rea, burden of proof, strict liability offence
The physical element of a crime: the conduct, act, or legally relevant omission that the prosecution must prove, together with its circumstances and consequences, beyond reasonable doubt.
- mens rea
- Related: actus reus, strict liability offence, criminal negligence
The mental element of a crime, such as intention, recklessness, or negligence. Except for strict liability offences, the prosecution must prove the accused held the required state of mind.
- strict liability offence
- Related: mens rea, actus reus, summary offence
An offence where the prosecution need not prove mens rea; proof of the prohibited act alone suffices. Common for traffic and regulatory matters, though defences of honest and reasonable mistake may apply.
- burden of proof
- Related: standard of proof, presumption of innocence, actus reus
The obligation on a party to prove a fact in dispute. In criminal trials the prosecution bears this burden and must satisfy the criminal standard of proof.
- standard of proof
- Related: burden of proof, presumption of innocence
The degree of certainty required to discharge the burden of proof. Criminal guilt must be established beyond reasonable doubt; civil liability is decided on the balance of probabilities.
- presumption of innocence
- Related: burden of proof, right to silence, bail
The principle that an accused person is treated as innocent until the prosecution proves guilt. It underpins bail considerations, trial procedure, and the right to silence.
- summary offence
- Related: indictable offence, committal hearing, strict liability offence
A less serious criminal matter heard by a magistrate alone in the Local Court, without a jury, and carrying limited maximum penalties such as imprisonment of up to two years.

- Related: summary offence, committal hearing, charge negotiation
A serious criminal matter ordinarily tried on indictment before a judge and jury in the District or Supreme Court, attracting heavier maximum penalties than summary offences.
- committal hearing
- Related: indictable offence, summary offence, legal aid
A Local Court proceeding in which a magistrate decides whether the prosecution evidence is sufficient for a serious matter to proceed to trial in a higher court.
- charge negotiation
- Related: indictable offence, mandatory sentencing, sentencing discretion
Also called plea bargaining: an arrangement where the accused agrees to plead guilty, often to a reduced charge or with fewer counts, in exchange for a lighter outcome.

Government-funded legal assistance for people who cannot afford representation, subject to means and merit tests. Access is limited and many accused remain unrepresented.

- Related: remand, presumption of innocence, crime prevention
The conditional release of an accused person into the community while awaiting trial or sentence. Australian law now emphasises unacceptable risk and, for some offences, a show cause requirement.
- remand
- Related: bail, presumption of innocence, recidivism
Detention in custody of an accused person who has been refused bail or cannot meet bail conditions, pending trial or sentencing. Remandees are legally presumed innocent.

Laws that fix a minimum penalty for particular offences, removing or limiting judicial discretion. Critics argue such laws can produce unjust outcomes and breach proportionality.
