Public Liability Insurance: The Essential Guide for Australian Builders [2025]

“I never thought it would happen on my site.”

That’s what most builders say after facing a public liability claim.

Whether it’s a falling tool that damages a car, or a visitor who trips on your site – one incident can cost you thousands.

Last year alone, the average claim in Australia hit $84,000.

What Does Public Liability Actually Cover?

Let’s cut through the insurance jargon. Here’s what you’re really getting:

You're Covered For:

  • Someone gets injured on or near your site
  • Your work damages someone else’s property
  • Accidents involving the public
  • Legal costs if you’re sued for these issues

You're Not Covered For:

  • Your workers getting injured (that’s WorkCover)
  • Advice you give clients (you need Professional Indemnity for that)
  • Your tools getting stolen
  • Vehicle accidents

How Much Coverage Do You Actually Need?

Different states have different rules. Here’s what you legally need:

State-by-State Requirements

StateMinimum RequiredWhat You Really Need
QLD$20M$20M minimum for QBCC
NSW$5M$10M+ recommended
VIC$5M$10M+ recommended
WA$5M$10M+ recommended

Pro Tip: Most builders carry more than the minimum. Here’s why:

  • Major projects often require $20M+
  • Higher coverage isn’t much more expensive
  • One big claim can exceed minimum coverage

Example Scenarios: When Public Liability Protects You

Scenario 1: The Shopping Centre Incident

The Situation:

  • Renovation work at a busy Brisbane shopping centre
  • Working after hours to minimise disruption
  • Safety barriers and signage in place

 

What Happened:

  • Water from cleaning work seeped into an adjacent store overnight
  • Damaged $85,000 worth of designer clothing stock
  • Store had to close for 3 days during peak season

 

Why It Could Happen to Anyone:

  • Even with proper precautions, accidents occur
  • Multiple stakeholders involved
  • Working in occupied buildings is high-risk

 

The Insurance Response:

  • Covered stock replacement costs
  • Paid store’s lost income claim
  • Handled all legal communications
  • Builder only paid agreed excess

 

Lesson Learned: Even with best practices in place, accidents can happen. Without public liability insurance, this common situation could have cost the builder over $120,000.

Scenario 2: The Residential Development

The Situation:

  • Building six townhouses in suburban area
  • Well-established neighbourhood
  • Regular deliveries to site

 

What Happened:

  • Delivery truck damaged neighbour’s driveway
  • Caused cracks in concrete and damaged landscaping
  • Neighbour claimed existing damage worsened
  • Relationship became hostile

 

Why It Could Happen to Anyone:

  • Tight access is common in residential areas
  • Neighbours often look for pre-existing damage
  • Multiple contractors coming and going
  • High-traffic areas during construction

 

The Insurance Response:

  • Independent assessment arranged
  • Negotiated with neighbour
  • Covered repair costs ($28,000)
