The decision is the drop zone
Every removal method exists to solve one problem: getting a large mass of timber to the ground without hitting anything.
If there is open ground at least as long as the tree is tall - acreage at Beerwah, a paddock, a cleared building site - the tree can be felled whole and the job is quick. If there is not, which describes most suburban blocks on this coast, the tree comes down in pieces and the job takes several times as long.
That single distinction explains most of the variation in what removals cost.
Method one: straight felling
The tree is cut at the base and falls in one piece in a controlled direction.
A notch is cut into the side facing the fall, a back cut is made slightly above it, and a strip of hinge wood is left uncut to steer the tree all the way down. Wedges or a rope high in the canopy correct for back lean.
It is fast, cheap and requires the most space. It is also where most DIY removal accidents happen, because a tree with any lean at all does not go where an untrained person expects. The technical detail is here.
Method two: sectional dismantling
The standard method on a suburban block.
A climber ascends on rope and harness and removes the tree from the top down. Small branch material is dropped into a cleared zone. Anything with weight is rigged - tied off above the cut, cut free, then lowered under friction through a device at the base so it descends under control rather than free-falling.
Once the canopy is off, the stem is cut down in rounds, each either dropped or lowered.
This is slow, skilled work and it is why a mature tree in a backyard costs what it does.
Method three: crane-assisted removal
Where a crane can set up on the street or driveway and reach the tree, it changes the economics.
Sections are slung, cut free, and lifted straight out of the canopy to a landing area or directly onto a truck. Nothing travels through the yard. A job that would take a climbing crew a full day can be done in a few hours.
The constraints are access for the crane, room for the outriggers, and overhead clearance. On tight streets around Mooloolaba or steep ground at Noosa Heads it is often impossible.
Method four: elevated work platform
A boom lift places the operator in the canopy without climbing it.
The main use is dead trees. When a tree has been dead long enough that no union can be trusted, putting a climber in it is not defensible, and the platform takes the weight instead. It is also used for working out over a roof or a pool where a climber could not get a safe position.
It needs firm, level ground within reach of the tree, which rules it out on a lot of sloped blocks.
After the tree is down
The stump is a separate decision - grinding or excavation, depending on what is going over the top of it.

Frequently asked questions
What decides which removal method is used?
The drop zone, almost entirely. If there is clear ground at least as long as the tree is tall, it can be felled in one piece. If not, it has to come down in sections. Size, species and health influence the detail, but the space underneath the tree is what decides the method and therefore the price.
Why does a crane make a removal cheaper sometimes?
Because it collapses a full day of rigging into a few lifts. Where a crane can reach the tree from the street, large sections are picked straight out of the canopy and set down on the ground or onto a truck. The crane hire is expensive per hour but the job may take a quarter of the time.
What is an elevated work platform used for?
Reaching a tree that cannot be safely climbed - usually a dead one, where no union can be trusted with a climber's weight. It is also used where the crew needs to work out over a structure. It needs firm level ground to set up on, which rules it out on many sloped Sunshine Coast blocks.
Is a tree removal messy?
Temporarily. Branch material is chipped on site, so there is a chipper running for part of the day and a truck filling with chip. Timber is cut and carried out. A reasonable crew rakes the site down before leaving and the lawn recovers, though machinery tracks on wet ground can take a season to grow out.
