PCBU Primary Duty of Care in the Northern Territory

What it is

The Northern Territory adopted the model Work Health and Safety framework as the Work Health and Safety (National Uniform Legislation) Act 2011 (NT) with commencement on 1 January 2012. NT WorkSafe administers the framework.

The NT enacted industrial manslaughter as a specific offence in 2020 amendments. NT construction industry compliance also interacts with the Building Practitioners Board framework under the Building Act 1993 (NT).

Section 19 primary duty

Section 19 of the WHS Act 2011 (NT) requires a PCBU to ensure, so far as is reasonably practicable, the health and safety of workers and other persons who could be exposed to risks arising from the work. The NT framework aligns with NSW, QLD, SA, TAS, WA and ACT.

Section 18 reasonably practicable

Section 18 defines reasonably practicable using the standard five-factor test.

Officer accountability

Section 27 imposes personal due diligence duties on officers. NT WorkSafe prosecutes officers less frequently than larger jurisdictions but the statutory framework is identical.

Industrial manslaughter (section 34B)

The NT enacted industrial manslaughter as a specific offence under section 34B of the WHS Act 2011 (NT) in 2020 amendments. The offence applies where a PCBU or senior officer engages in conduct that constitutes a failure to comply with a health and safety duty and that conduct causes the death of a person.

Penalties: individual up to life imprisonment. Body corporate up to $15.5 million. The individual life imprisonment maximum is distinctive to the NT; other Australian jurisdictions cap at 20 to 25 years.

Category offences

Category 1 (section 31) up to $600,000 or 5 years imprisonment individual / $3,000,000 body corporate. Category 2 (section 32) up to $300,000 individual / $1,500,000 body corporate. Category 3 (section 33) up to $100,000 individual / $500,000 body corporate.

Notification framework

The NT reg 292 construction project trigger sits at $1,000,000, amended on 28 May 2026 by SL No. 14 of 2026. That threshold is higher than most states (SA $450,000, ACT $250,000, TAS $250,000) and gives NT residential builders more work below the trigger.

The trigger determines when notifications and additional duties attach for construction projects.

Cost plus prohibited

The Building Regulations 1993 (NT) prohibit cost plus contracts by requiring every prescribed residential building contract to specify a total contract price. That builds interaction between the WHS Act and the Building Act frameworks.

Interaction with building framework

WHS Act breaches by an NT builder can trigger Building Practitioners Board disciplinary action alongside NT WorkSafe enforcement. The Commissioner for Residential Building Disputes can also make orders for compensation flowing from safety-related workmanship failures.

TradeForm NT templates flag WHS Act 2011 (NT) compliance as critical for residential builders, particularly the industrial manslaughter offence and the reg 292 project trigger.

How the Northern Territory compares

The NT's section 19 duty aligns with other model WHS jurisdictions. The distinctive NT features are:

• individual life imprisonment maximum for industrial manslaughter under section 34B (unique in Australia)
• $15.5 million body corporate maximum for section 34B
• reg 292 construction project trigger at $1,000,000 (highest in Australia)
• interaction with the Building Practitioners Board framework and Fidelity Fund NT

The NT small market size means fewer prosecutions but the statutory framework carries the full force of the model WHS Act.
