The legislation library now covers dangerous goods and dangerous substances regimes across NSW, Queensland, Victoria, WA, SA, Tasmania, the ACT and the Northern Territory. This gives warehouses, manufacturers, labs, farms, retailers, hospitality operators, builders, importers and logistics businesses a clearer place to understand classification, packaging, placarding, transport documents, emergency information, storage, handling, licences, notices and incident records.
The legislation library now covers key licensed-trades and technical-safety regimes for electrical, plumbing, drainage, gasfitting and utility work across Australia. This gives trade contractors, builders, fitout teams, landlords, franchise groups and small businesses hiring contractors a clearer place to understand licence classes, certificates, inspections, incident records, regulator notices and handover evidence.
The legislation library now has a state and territory building-regulation cluster covering builder and trade authorisation, fitout projects, permits, inspections, certifiers, handover records and contractor due diligence. This is designed for builders, tradies, landlords, tenants, franchisors and small operators opening or renovating premises.
This batch adds official NSW explainers for business sale finance adjustments, lease assignment consent, clinic confidentiality and restraint disputes, statutory demands, rural planning approvals, construction payment claims and payroll tax grouping. The practical theme for small businesses is documentation: write the deal clearly, keep the evidence, and handle consent, payment, tax and exit processes before they become court problems.
Businesses can now browse the core planning and premises approval laws for every state and territory, plus the federal Premises Standards for building accessibility. The pages focus on leases, fitouts, changes of use, development approvals, signs, access, building checks and local authority conditions.
Businesses can now browse core environmental compliance laws for the Commonwealth, every state and territory, and the NT's separate waste and pollution control law. The pages focus on premises, projects, waste, noise, pollution incidents, approvals, contractor controls and regulator notices.
Business owners now have richer selected-case explainers for product safety claims, restricted-purpose funding, company reinstatement, restructuring deeds, shareholder litigation planning, director duties, construction contracts, misleading loan promises, fuel advertising and consumer guarantee claims after resale.
This repealed building-industry source belongs in Fair Work history because construction-sector workplace regulation has changed names, bodies and enforcement settings over time. Small construction businesses should not rely on it as current law. It is useful context when reviewing older contracts, compliance notices or disputes that refer to the earlier building-industry framework.
