The Gold Coast to Byron Bay.

Broadwater-front canal homes, body-corporate low-rise, and the older brick-and-render streets behind Chirn Park and TSS.

Canal-front homes, holiday-let apartments and the low-rise blocks behind the beachfront — salt-aware exterior work, honestly scoped.

Broadbeach Waters canal homes, low-rise strata blocks, and the older streets behind the dining precinct — salt-aware exterior work on a schedule.

Hinterland acreage, leafy established streets and bushfire-interface gutters — the inland half of the corridor, where it's mould and leaf litter, not salt.

Headland-exposed beach homes, the national-park bushland edge, and the renovated cottages climbing the hill — salt and leaf litter in the same suburb.

Original fibro beach shacks next door to architect-designed rebuilds — a fast-changing strip where the surfaces vary wildly house to house.

From the exposed points and the estuary to the valley acreage — Currumbin runs coast to hinterland, and the work changes the further up you go.

The exposed border points, the holiday-let blocks above the beach, and the streets along the airport — some of the heaviest salt exposure on the corridor.

Coastline Restoration Co. works across Tweed Heads, Tweed Heads South, Banora Point and the river precinct. Salt off Colorbond, mould off render, gutters cleared before the next big easterly.

Hill-house roofs, mature-gum gutter problems, and the view-aspect maintenance most of Banora Point quietly needs.

Hinterland houses, acreage blocks, and the big-rain wear pattern from Mount Warning to the river flats.

Coastal-salt exteriors, newer-build complexity, and holiday-rental presentation across Kingscliff and the Salt-Casuarina coastal strip.

Beach-house exteriors, holiday-rental presentation, and cocos-palm-clogged gutters across Cabarita, Bogangar and the headland.

Family coastal blocks, bushland-interface properties, koala-corridor pruning rules respected across Pottsville and Black Rocks.

River-mouth cottages, holiday rentals and the old fishing-village fabric — coastal salt and estuary humidity in a tightly-held Byron Shire town.

Heritage village cottages and hinterland acreage in the green hills behind Byron — no salt out here, just leaf litter, mould and the shire's tree rules.

Holiday lets, high-end coastal builds and the salt-and-humidity double hit — Byron's a presentation town with the strictest tree rules on the corridor.

The quieter family-and-beach-house side of Byron, against Arakwal National Park — salt, humidity and the same strict shire tree rules.
