Three environments in one suburb
Caloundra packs three quite different conditions into a few kilometres.
The headlands - Kings Beach, Shelly Beach, Moffat Beach - are the most exposed ground on this stretch of coast. Salt, wind and thin soil over rock. Trees here are stunted, leaning and shallow-rooted, and when they fail the root plate lifts rather than the stem breaking.
Golden Beach and Pelican Waters sit behind Bribie Island on Pumicestone Passage, far more sheltered, with sandy flats and canal frontages. Trees grow better and the problems are more about size and proximity than exposure.
Inland at Little Mountain and Caloundra West you are on newer estate blocks with landscape plantings from the nineties and two thousands, now hitting the size their planters did not think about.
Norfolk Island pines
They are the signature of the Caloundra foreshore and they need particular handling. A Norfolk has one leader and a rigid architecture of horizontal whorls. Topping it destroys the form permanently and creates a cluster of competing leaders that are weakly attached and eventually fail.
What can be done is deadwood removal, lifting the lower whorls for clearance, and dealing with storm-damaged limbs. What cannot be done is height reduction. If a Norfolk is genuinely too tall for its position, the choice is to live with it or remove it - not to shorten it.
Pandanus and coastal natives
Pandanus along the foreshore is protected in practice as well as in policy, and it also carries a pest problem: pandanus planthopper causes the dieback you see in crowns along this coast. That is a treatment question rather than a pruning one, and topping a struggling pandanus finishes it off.
Tuckeroo, coastal banksia and cottonwood make up much of the rest. All handle salt, all drop deadwood, none need heavy work.
What we do most here
Deadwood and clearance work on Norfolks and coastal natives. Removal of failed or leaning trees after storms on the headlands. Reductions on the bigger inland plantings at Little Mountain. Stump grinding in sandy soil, which is quick - sand grinds far faster than the basalt-grown timber up the range.

Frequently asked questions
Can Norfolk Island pines be pruned?
Only lightly, and never topped. Norfolk Island pines have a single dominant leader and a rigid whorled branch structure. Cut the leader and the tree never recovers its form, and the replacement leaders that compete afterwards are weakly attached. Deadwood removal and clearance pruning of lower whorls are the sensible limit.
Why do trees fail on the headlands?
Sustained onshore wind plus shallow rooting. Around Kings Beach, Shelly Beach and Moffat Beach the soil profile over rock and sand is thin, so trees anchor poorly, and the constant wind load means they carry a permanent lean. When one fails it is usually the whole root plate lifting rather than a stem breaking.
Is Caloundra under Sunshine Coast Council?
Yes. Caloundra, Golden Beach, Pelican Waters, Currimundi, Little Mountain and Caloundra West are all Sunshine Coast Council. The planning scheme vegetation overlays apply, and there are protection orders on individual trees, particularly the older street plantings.
