Understand the complete water system.
Water sources, storage, treatment and household demand vary between properties. Check how the system works as a whole and whether it suits the expected use.
Is the property connected to mains water, rainwater tanks, a bore, a dam or a combination? Confirm tank capacities, roof catchment area and which sources supply drinking water, gardens, livestock and fire protection. Suitable storage depends on household demand, occupancy, rainfall, catchment and backup arrangements.
Check the visible condition of tanks, liners, screens, first flush devices, gutters, downpipes, pumps, filters and treatment equipment. Ask about maintenance, faults, replacement history and what happens during a power failure or equipment breakdown.
Ask how drinking water is treated and whether recent laboratory testing is available for tank or bore water. Water quality can change over time, and a clear appearance does not confirm that water is suitable for drinking. Arrange testing where appropriate.
If a bore, dam or surface water source is important to the property, confirm available records, equipment condition, seasonal reliability and any approvals, licences or other rights that may apply. A previous owner's experience does not guarantee future yield or water quality.
Understand the onsite wastewater system.
A property outside the sewer network may rely on an onsite wastewater facility. Its approval, capacity, condition and land application area can affect everyday use and future plans.
Identify the type and location of the wastewater facility and land application area. Ask for the original approval, plans and applicable conditions. Confirm the approved capacity and whether it reflects the current number of bedrooms and use of the property.
Ask for available service reports, pump out records, repair history and details of the service provider. Treatment plant servicing intervals depend on the individual system and approval conditions. Confirm what is required rather than assuming every system follows the same schedule.
Look for ponding, runoff, odour, damaged irrigation, unusually wet ground or stressed vegetation. Check whether the area has been built over, driven across or used in a way that conflicts with the approval. An extension, additional bedroom or secondary dwelling may require the wastewater arrangements to be reassessed.
Check the legal and practical access.
Access may involve private roads, shared driveways, easements, steep terrain, creek crossings or drainage constraints. Check both the legal arrangement and how access performs in different conditions.
Ask a solicitor or law practice to review the title, survey plan, easements and any other documents affecting access. Where access crosses another property, confirm the rights granted and any limitations or obligations.
Establish who owns and maintains each part of the access. Review any documented arrangements for maintenance, drainage, repairs and shared costs. Do not rely only on an informal description from the seller or agent.
Inspect the full route where possible. Consider width, gradient, surface, turning areas, gates, erosion and overhead clearance. Check whether removal vehicles, service vehicles, construction deliveries and emergency vehicles can reach the relevant parts of the property.
Ask about road closures, creek crossings, flood isolation, washouts and previous access problems. Inspect culverts, table drains and visible runoff paths. Council mapping and available records should be checked rather than relying only on recollections.
Understand the hazards affecting the site.
Bushfire, flooding, landslide and difficult access can influence future building work, insurance and how the property may perform during an emergency.
Confirm whether the property is mapped as bushfire prone. A Bushfire Attack Level, commonly shortened to BAL, is assessed for a building location using factors such as vegetation, slope and separation distance. It is not a permanent rating for the entire property.
Check available building approvals and records for existing structures. Current bushfire construction requirements are not automatically retrospective. If building or substantial alteration is planned, obtain advice about the assessment and construction requirements that may apply to the proposed work.
Consider emergency access and exit routes, available firefighting water, surrounding vegetation and any bushfire plan or approval conditions applying to the property. Also check flood, coastal and landslide mapping where relevant. Obtain insurance quotations for the specific address before signing the contract.
Confirm what can be used or changed.
Zoning, overlays, vegetation laws, existing approvals and physical land constraints can affect how a hinterland property may be used or developed.
Confirm the applicable local government, zoning and planning overlays. Check whether the intended residential, agricultural, business, animal keeping, accommodation or development use is permitted and whether approval may be required.
Request a current Queensland vegetation management property report and check whether a certified Property Map of Assessable Vegetation, commonly shortened to PMAV, exists. A PMAV identifies vegetation category boundaries where one has been certified. It is not the only source of clearing restrictions.
Where clearing appears recent, ask for available approvals, notifications or evidence of an applicable exemption. Obtain legal, planning or vegetation advice where the position is unclear. Do not assume the absence of vegetation proves that clearing was lawful.
Review available records for the dwelling, sheds, cabins, pools, retaining walls, earthworks and other improvements. Confirm whether the current use of each structure is approved and whether any approval conditions affect the property.
Check surveyed boundaries where their location matters. Inspect fencing, gates, dams, waterways, steep areas and retaining structures. Consider whether livestock, maintenance, erosion, drainage or planned land use requires further specialist advice.
Check the services you will rely on.
Electricity, telecommunications, waste collection, fuel supply and construction access can vary considerably between properties. Confirm what is actually available at the address.
Establish whether the property is connected to the electricity network or relies partly or entirely on solar, batteries or a generator. Ask for available records, equipment details and maintenance history. A qualified professional should assess private electrical equipment where required.
Check which internet and mobile services are available at the address and test them where practical. Coverage maps are only a starting point. Consider the needs of everyone who will live, work or operate equipment from the property.
Confirm rubbish and recycling arrangements, liquefied petroleum gas (LPG) supply where applicable, postal and courier access and the ability of service vehicles to reach the property. Obtain estimates for planned construction or renovation based on the individual property's access, terrain, services and required approvals.
Hinterland due diligence is about understanding how the land, buildings and private infrastructure work together. The relevant checks depend on the property and the buyer's plans, so unresolved matters should be investigated before the applicable contract deadlines.
