Buying a home near a former coal mine does not have to mean stepping into the unknown. Queensland has well-documented records of historical mining activity, a free mapping tool, and a government guarantee specifically designed to protect affected homeowners in one of the state's most closely watched suburbs.
The key is knowing which searches to run, what they actually show, and what they cannot tell you. A title search reveals registered interests, but it will not tell you whether the ground beneath a property was mined a century ago. For that, buyers need a different set of checks, and understanding the distinction early makes a real difference to how a contract is approached.
Our solicitors in Springfield and Ipswich help clients across Greater Springfield with property purchases in areas where mining history is a genuine consideration. Here is how the checks generally work in Queensland, and what the Collingwood Park rules mean for buyers and sellers in that area.
Here is how historic coal mining searches and subsidence protections generally work in Queensland, and what they mean for a property contract.
Key takeaways
- Queensland's GeoResGlobe tool maps historical mining activity across the state for free.
- The State guarantees repair or purchase for Collingwood Park homes affected by mine subsidence.
- Historic mining records are incomplete, so a clear search does not confirm a property is unaffected.

What do historic coal mining searches reveal in Queensland?
An undermining report generated on GeoResGlobe, the Queensland Government's free online mapping tool, shows historical mining activity records for an area, according to Business Queensland. It can be a useful early indicator that underground coal workings may be present beneath or near a property.
The important caveat is that the State's historical records on abandoned mines are incomplete and their reliability is not guaranteed. A clear result on GeoResGlobe means no mining activity has been recorded for that area, not that mining never occurred. Buyers in regions with a coal mining history generally treat this search as one layer of due diligence, not a definitive answer.
Beyond GeoResGlobe, the Queensland Government notes that areas and properties with underlying historical mine workings can also be found by searching the Ipswich City Council planning website, where known mining influence areas are mapped. For properties in suburbs such as Collingwood Park, Redbank Plains and surrounding parts of Greater Ipswich, checking council's mapping alongside the state tool gives a more complete picture.
What is the Collingwood Park mine subsidence situation?
Part of Collingwood Park sits over two decommissioned underground coal mines, the Westfalen Number 3 and New Redbank collieries, according to the Queensland Government. The suburb experienced subsidence events in December 1988 and April 2008, both of which caused surface movement and damage to houses.
Ground monitoring sensors have since been installed in the area. The Queensland Government's data indicates the ground is currently stable, though monitoring continues as the State's ongoing responsibility for the Abandoned Mine Lands Program.
For buyers considering a property in Collingwood Park, understanding what the State guarantee covers, and what it does not, is an essential part of the decision.
What does the Queensland State guarantee cover for Collingwood Park?
The State has guaranteed to repair any property in Collingwood Park that is affected by mine subsidence-related damage, or to buy it at market value if repairs are not cost-effective, according to the Queensland Government and the Mineral Resources Act.
The guarantee applies to land that on 5 November 2008 was part of Collingwood Park and was used only for a residential, charitable or religious purpose. Subsidence damage for these purposes means damage to the affected land, or to any buildings or structures on it that were in existence at the beginning of 25 April 2008, caused by or related to subsidence resulting from mining activity.
An owner of affected land may ask in writing to have the guarantee recorded on the freehold land register, so that a title search of the register shows it, according to the Mineral Resources Act. That means a buyer can, in principle, identify whether the guarantee is noted on a title they are considering purchasing.
What the guarantee does not cover includes buildings or structures erected after 25 April 2008, property outside the defined Collingwood Park area, or subsidence damage in other suburbs or from other causes. No official source describes the guarantee as applying anywhere other than Collingwood Park, or to any event other than the two recorded subsidence periods.
"In Queensland, a property's mining history does not appear on a standard title search. Buyers need to run a separate undermining report and check council mapping to understand what, if anything, sits beneath a property."

When does subsidence history appear in the seller disclosure rules?
Queensland's seller disclosure scheme, which commenced on 1 August 2025 under the Property Law Act 2023, requires sellers to give buyers a signed disclosure statement before a contract of sale is signed, according to the Queensland Government.
The statement covers certain matters including transport infrastructure notices and resumption notices, heritage listing and environmental register listing. However, the scheme does not require the seller to disclose the presence of underground mine workings, historic flooding from subsidence or general geological conditions.
What the seller does disclose under the scheme is whether the lot is listed on the Environmental Management Register or Contaminated Land Register, and whether any relevant Building Act or Planning Act notices have been given. A mining influence area shown in a council planning overlay may appear through the planning-related fields, but a buyer generally cannot rely on the seller's disclosure statement as a complete picture of subsidence risk. Independent searches remain important.
The Queensland Government's guide to the seller disclosure scheme notes that for matters not covered by the statement, buyers make their own enquiries. Mining history and subsidence risk sit firmly in that category.
How do mining and subsidence checks work as part of a Queensland property purchase?
Step 1: Talk to us
Get in touch and we will explain how the process generally works and what searches are typically relevant for the area you are buying in.
Step 2: Run the relevant searches
We run an undermining report through GeoResGlobe and review available council mapping for mining influence areas. We also conduct a title search, which shows whether the State guarantee has been recorded on a Collingwood Park property's register entry.
Step 3: Review the seller disclosure documents
We review the seller disclosure statement and the prescribed certificates the seller must provide before you sign. We check what environmental register, planning notice and council information is included, and identify any gaps that warrant follow-up.
Step 4: Advise on the contract
We advise on what the search results mean for the contract. Our conveyancing team can help structure the contract appropriately for the property's circumstances and ensure your position is protected through to settlement.

What do mining searches not show?
Understanding the limits of each search tool is as important as running the searches themselves. GeoResGlobe maps records from the State's historical database, but Business Queensland is explicit that those records are incomplete and their reliability is not guaranteed. A property could have been undermined without any formal record existing at all.
A standard title search does not show underground mine workings. It shows the registered owners, mortgages, caveats, easements and covenants on a title, but geological conditions beneath the land are not recorded interests and will not appear. Similarly, a pre-purchase building inspection looks for observable defects in the structure, not for subsidence risk beneath the slab or foundations.
Council planning website searches show known mining influence areas that council has mapped and included in its scheme. However, the mapped areas reflect what has been formally recorded and assessed, not every area where historic mining occurred. For properties on the fringe of a mapped area, or in older suburbs where records are patchy, the absence of an overlay is not a guarantee.
Frequently Asked Questions
Is a GeoResGlobe undermining report enough to assess subsidence risk in Queensland?
Generally not on its own. Business Queensland notes that the State's historical mining records are incomplete and their reliability is not guaranteed, so council mapping and a title search are also useful parts of the picture.
What is the Queensland Government's Collingwood Park guarantee, and who does it cover?
The State guarantees to repair subsidence damage to Collingwood Park properties, or buy them at market value if repair is not cost-effective, according to the Queensland Government. It applies to land used for residential, charitable or religious purposes as at 5 November 2008, and to buildings in existence as at 25 April 2008.
Does the Collingwood Park guarantee apply to buildings built after April 2008?
No. The guarantee under the Mineral Resources Act covers buildings and structures that were in existence at the beginning of 25 April 2008. Structures built after that date are not covered by the same guarantee.
Will the seller disclosure statement tell a buyer about coal mine workings in Queensland?
Not directly. Queensland's seller disclosure scheme, which commenced 1 August 2025 according to the Queensland Government, does not require a seller to disclose underground mine workings. Buyers make their own enquiries about subsidence risk through separate searches.
Can a buyer check whether the State guarantee is noted on a Collingwood Park title in Queensland?
Yes. The Mineral Resources Act allows an owner to ask in writing for the guarantee to be recorded on the freehold land register, so a title search can show it. A solicitor can conduct that search as part of the conveyancing process.
Do buyers in Springfield or Ipswich QLD need a solicitor to run coal mining and subsidence checks?
A solicitor does not run the GeoResGlobe search itself, but plays an important role in interpreting results, reviewing council mapping, checking the title and seller disclosure documents, and advising on how any mining history should be addressed in the contract. A solicitor can advise on what the findings mean for a particular purchase.
Does a clear building inspection mean a property has no subsidence issues in Queensland?
Not necessarily. A pre-purchase building inspection looks for observable defects in the structure, not for geological conditions below the surface. Mining searches through GeoResGlobe and council mapping are separate steps that a building inspection does not replace.
Your Next Steps
Buying a property in an area with a coal mining history requires a broader set of checks than a standard residential purchase in Ipswich or Greater Springfield. The searches are available, the information is accessible, and Queensland's records, while incomplete, provide a genuine starting point for understanding what lies beneath a site. Getting the right searches in place before a contract is signed, rather than after, is what keeps buyers in the strongest position.
Every property purchase is different, and that's exactly why it's worth a conversation. Make an appointment with the Brookwater Legal team or call (07) 3437 8555.
