Source ledger / Buyer voice · regulators · standards · manufacturers

Every source behind the consumer guide — named, grouped, and where possible linked.

A trade guide is only as trustworthy as the sources behind it. This ledger lists where the research came from in six categories — from the homeowner forums that supplied the verbatim voice, through to the operator quote verification that anchors every price band.

Buyer voice

4,300+

Verbatim homeowner quotes across 11 source types

Regulators cited

State and federal bodies cross-referenced

Operators verified

Pricing-quote operators across 7 regions

How to use this

The ledger groups sources by type. For each, we list what it's used for, the approximate weight in the research, and (where applicable) a verified link. For the full methodology — how these sources were collected, clustered, and verified — see /methods.

Buyer voice (the homeowner research)

The 4,300+-account collection is sourced from public-facing platforms where Australian homeowners describe trade experiences in their own words. We use only publicly-visible content. Approximate share of the collection shown for each.

Verified-purchase reviews tagged by service category, with operator response visibility.

Google Reviews (publicly indexed) ~10%

Operator-specific reviews indexed via business listings, weighted toward localised experience.

CHOICE community forum & help pages ~6%

State fair-trading complaint summaries (where publicly published) ~3%

Aggregated public summaries; we do not access individual complaint records.

Other (trade association forums, industry publications, archived sources) ~5%

Long-tail of specialised sources, each contributing small absolute volume.

Manufacturer documentation

Where the guides cite manufacturer warranty terms or product specifications, we work from the manufacturer's published technical documentation. Our summaries are general — read the actual warranty document supplied with your installation for full terms.

BlueScope Steel — Colorbond warranty documentation

Spray Seal Australia — soft-wash chemistry documentation

Hypochlorite and biocide formulation guidance for soft-wash roof and render cleaning.

Operator pricing verification

Every published price band is cross-checked against three operator quotes per state per band, dated within the rolling 12 months. Approximate geographic distribution:

Region	Operators	What was verified
NSW — Sydney metro	~28 operators	Quote verification across all 33 trade categories, dated Aug 2025 – Apr 2026.
NSW — regional (Hunter, Illawarra, Central Coast)	~12 operators	Quote verification with regional pricing modifiers.
VIC — Melbourne metro	~22 operators	Quote verification across 33 trade categories.
VIC — regional (Geelong, Bendigo, Mornington)	~9 operators	Regional pricing verification.
QLD — Brisbane / Gold Coast	~18 operators	Quote verification across 33 trade categories.
QLD — regional (Sunshine Coast, Townsville, Cairns)	~6 operators	Cyclone-zone uplift and tropical pricing verification.
WA, SA, TAS, NT, ACT	~8 operators	Smaller-volume verification, biased toward the trades with greatest state-by-state variance (builders, demolition, scaffold).

Operators participating in pricing verification are not named — both because we don't pay them, and because we don't want pricing verification to be confused with operator recommendation. Different operators participate across different trades and refresh cycles.

Sample evidence packs

Category weights are one thing; the raw material is another. Below is a small, representative sample of the public buyer verbatims behind a few major trades — each with its source type, state, the issue cluster it fed, and why it mattered. Every one already appears, in context, in the linked trade guide.

Roofer

/roofer →

“Just got a quote online, around $3,000. My neighbour just did and cost him $9,000. The price seems big difference.”

Whirlpool NSW · Quote spread

Why it mattered: A 5× spread on the “same” job almost always means the quotes are pricing different scopes — repair vs restoration.

“He is a sole trader, doesn't have a website, and no reviews on his FB page. Does have an ABN, but no idea what qualifications to check on.”

Whirlpool NSW · Verification

Why it mattered: Missing trust signals aren’t disqualifying — but they must be made up for with a licence and ABN check.

“I paid them in full towards the end of the day trusting they would complete the job. I now cannot get them to come back and finish. No invoice has been issued either.”

Whirlpool NSW · Payment & completion

Why it mattered: Paying before sign-off and paperwork removes the only leverage you have.

Electrician

/electrician →

“What certificate / forms / warranties should I be asking from electrician?”

Reddit NSW · Certificates

Why it mattered: The CCEW (NSW) or COES (VIC) is the proof the work is compliant and your insurance stays valid.

“Watch out for extremes — both very high and very low quotes are red flags.”

Reddit NSW · Quote spread

Why it mattered: The cheapest quote often hasn’t priced the compliance work; the dearest may be padding.

Painter

/painter →

“Some of the quotes I got are just pure stupidity.”

Reddit · r/sydney NSW · Quote spread

Why it mattered: The spread comes from prep scope — one painter prices two coats over real prep, another prices a refresh.

“I include washing the surface in my quote. Too risky to go off someone else's word… I'm liable.”

Operator voice — · Prep & liability

Why it mattered: The prep line is where margin and risk live; a quote that omits it is hiding the real job.

Builder

/builder →

“Builder wants 50% deposit upfront in Sydney NSW, is this normal?”

Whirlpool NSW · Deposit

Why it mattered: NSW caps residential deposits at 10% — 50% upfront is both illegal and a classic loss pattern.

“Our architect warned us prices could be as high as $4-5k per m², and the pricing from the builder came back closer to $6k!”

Whirlpool NSW · Scope & provisional sums

Why it mattered: Per-m² shock usually traces to inclusions and provisional sums that reconcile upward.

Pest control

/pest-control →

“Tried to follow up and he ignored me and ghosted me, as their solution didn't fix my pest problem.”

Reddit · r/melbourne VIC · Aftercare

Why it mattered: Post-job ghosting is the most repeated complaint across trades — the warranty and callback terms are the test.

These are a curated sample, not the full corpus. We publish verbatims only from public-facing platforms, lightly trimmed for length and stripped of any identifying detail. The complete 4,300+-account collection sits behind the guides themselves.
