Method one: mechanical grinding
The default for good reason. A carbide-toothed wheel reduces the stump and the top of the root flare to chip, typically 200 to 300mm below grade.
Fast, predictable, and it leaves the surrounding ground largely intact. It does not remove the deeper root system, which stays in the soil and decays over several years without causing problems.
Right for almost every domestic situation: turf, garden beds, paving, or simply getting rid of a trip hazard. How it works in detail.
Method two: full excavation
An excavator strips the soil back, severs the anchoring roots and lifts the stump and root plate out in one or two pieces. The whole assembly leaves the site and the hole is backfilled with clean fill and compacted in layers.
It is substantially more expensive and considerably more disruptive. It is also the only method that works when something structural is going over the footprint, when a root plate is damaging a wall or a pipe, or when a root-borne pathogen has to leave the property. The service page covers it.
Method three: manual removal
Digging around the stump, cutting the anchoring roots with a mattock, axe or saw, and levering the stump out.
Entirely feasible on a small stump - under about 250mm across, on a species without a massive root plate. Utterly impractical on a mature hardwood, where the root plate can be a couple of metres across and the anchoring roots are the thickness of your arm.
It is free apart from the tools and your weekend. A realistic account of the work is here.
Method four: chemical accelerants
Potassium nitrate products are sold as stump removers. The mechanism is real but indirect: the nitrogen feeds the fungi and bacteria that break timber down, speeding a process that would happen anyway.
The method involves drilling deep holes into the stump, filling them with the product, adding water and covering the stump to keep it moist. Then waiting - months at best, years for a sound hardwood.
It works best on a stump that is already partly decayed. On fresh spotted gum or ironbark it achieves very little. Keep pets and children away from treated stumps, and follow the label.
Epsom salt is the household variant of the same idea, working by drawing moisture out. Same verdict: slow and unreliable.
Method five: burning
Not recommended, and in most of the region not lawful.
Open burning in urban and residential areas is regulated and generally requires a permit. More importantly, a stump fire travels underground along root channels, where it can smoulder for days out of sight and re-emerge metres away. Fires started this way have destroyed sheds and fences.
Do not use it as a shortcut.
Choosing
For most people the choice is grinding, unless something structural is going over the top, in which case it is excavation. The comparison is set out here and cost drivers here.

Frequently asked questions
What is the fastest way to remove a stump?
Mechanical grinding. A stump that would take a weekend to dig out by hand and several years to rot with chemical accelerants is usually gone in under two hours with a grinder. For anything above about 200mm in diameter it is the clear choice on time alone.
Do chemical stump removers actually work?
Slowly, and only on some stumps. Potassium nitrate products accelerate decay by feeding the fungi that break down timber, but they take months to years and work best on a stump that is already partly rotten. They do nothing useful on sound hardwood, which is most of what gets cut down here.
Can I burn a stump out?
In most of the Sunshine Coast region, no. Open burning in urban and residential areas is regulated and generally prohibited without a permit, and a stump fire burns underground along root channels where it cannot be seen or easily extinguished. It is a genuinely dangerous method and it is not recommended anywhere.
Is Epsom salt a real method?
It is a widely repeated one. Magnesium sulphate draws moisture out of the timber and can speed drying and eventual decay, but the timeframe is years and it is unreliable. It will not remove a stump on any schedule that matters to someone wanting to lay turf.
