Palms are not trees, botanically or practically
A palm is a monocot. It does not have a cambium layer producing new wood each year, it does not branch, it does not thicken its trunk once established, and it has exactly one growing point at the very top of the stem.
Every practical consequence follows from that. Damage to the trunk never grows over. There is no crown to reduce. And cutting the top out does not make a smaller palm, it makes a dead palm. The only real options are tidying the fronds and removing the seed heads, or taking it out entirely.
The approval position
Many New South Wales councils list certain palms — cocos palm in particular — as exempt species that can be removed without a tree works application. Many do not exempt others.
The variables that matter: which council you are in, the species, the height, and whether the palm is part of a landscaping condition attached to a development approval. Across this service area three separate councils apply, and their lists are not the same — see the service areas page for which one governs your block.
The rule remains the same as for anything else: ring council with the address and the species and ask. Ten minutes now against a substantial penalty later, as set out in the approval guide.
The cocos palm problem
Cocos palm, Syagrus romanzoffiana, was planted by the thousand across coastal New South Wales from the 1970s onward and has turned out badly. It fruits heavily, birds and flying foxes spread the seed into bushland, and it has naturalised extensively along the coast. It is that ecological impact, rather than any feature of the plant in a garden, that has put it on weed lists.
In a domestic setting it is also a nuisance: constant frond drop, heavy slippery fruit onto paths and driveways, and rats and other vermin in an unmaintained crown. Most cocos palms in Illawarra yards are eventually removed rather than maintained.
Cabbage tree palms are different
Livistona australis, the cabbage tree palm, is a native and a normal component of the local vegetation, particularly in the moist gullies along the escarpment behind Figtree and Thirroul. It is not a weed, it is not generally exempt, and it should not be treated like a cocos.
If you have a tall palm and you are not sure which it is, find out before anyone cuts. It is the difference between an exempt removal and an unapproved removal of protected native vegetation.
How palm removal actually works
Small palms can be cut at the base and the stump ground like anything else. Tall ones are climbed with spikes or gaffs — which is acceptable on a tree being removed and not on one being kept — or worked from an elevated platform, and the stem is taken down in sections.
Palm timber is fibrous rather than woody, so it does not chip well, does not burn well and generally goes to disposal rather than becoming mulch or firewood. That shows up in the price as a disposal cost.
The other thing to know is that palm fronds are heavier than they look, and the frond bases on an unmaintained cocos are a favourite habitat for wasps. Neither is a reason not to do it; both are reasons not to do it off a ladder.

Frequently asked questions
Are cocos palms exempt from council approval?
Frequently, but you must check your own council's current list rather than relying on what applied five years ago or in another local government area. Cocos palm — Syagrus romanzoffiana — is widely treated as a weed species and appears on many exemption lists in New South Wales. Established garden specimens of other palms are often not exempt at all.
Why can't a palm just be pruned smaller?
Because palms have a single growing point at the top of the stem. Cut it off and the palm dies — there are no dormant buds along the trunk to produce new growth the way there are on a eucalypt. Palms also do not thicken their trunk over time or produce new stem tissue, so damage to the trunk never heals over. Reduction simply is not available.
Are cocos palms dangerous to wildlife?
They are widely regarded as a problem. The fruit is eaten by flying foxes and birds, which spreads the seed extensively into bushland, and there are long-standing concerns about the effect of the fruit on some species. That ecological impact is the main reason cocos palm turns up on weed lists and council exemption schedules across coastal New South Wales.
