Standard AU booking: 5-10 business days. Expedited 24-48 hours adds $50-$150. Same-day inspection adds $200-$400 (~$750-$1,100 total in metro). Weekends add 15-25% premium. Regional adds 3-5 days + travel surcharge. The constraint is almost never the inspector's diary — it's the access window, which typically needs 4-6 hours notice via the listing agent. If you're in cooling-off and the window is tight, book within 24 hours of contract signing to give yourself time to read the report and act.
What does this mean for your property?
This guide explains the general issue. Decode your own report for prioritised findings, repair cost estimates and questions to take to your inspector.
One-off payment · No account requiredYou signed the contract Saturday afternoon. The agent confirmed cooling-off started Monday. You have until Thursday 5pm to commission a building inspection, get the report, read it, and decide whether to walk.
That's 3 business days. The standard inspection booking window in Australia is 5-10 business days. The maths is immediately tight.
Here's realistic timing by city, by scenario, and what the expedite premiums actually cost — so you can make the booking call within 24 hours of signing.
Standard booking timeline
In every Australian capital city, the standard booking process is:
- Day 0: You contact 2-3 inspection firms with your property address and intended inspection date
- Day 1-2: Firms confirm availability + send quotes + arrange access with listing agent
- Day 3-7: Inspector attends the property, conducts inspection (60-120 min on site)
- Day 5-10: Report typed up and delivered via email (PDF)
Total standard window: 5-10 business days from contact to report. Cost: $550-$750 for combined building + pest inspection on a typical 3-bed metro house.
Expedited 24-48 hour
Most established metro firms offer expedited turnaround for a premium. Typical structure:
- Inspection within 48 hours of booking: $50-$100 expedite fee
- Inspection within 24 hours of booking: $100-$150 expedite fee
- Report delivered within 12 hours of inspection: additional $50-$100
Total expedited cost: $700-$1,000. The firms that genuinely offer 24-hour expedite are usually:
- Larger firms with 5-10 inspectors who can rotate schedules
- Firms that explicitly market expedite services on their website
- Firms with administrative staff who can write up reports same-day
Smaller solo-inspector firms typically can't expedite — they're booked solid for a week ahead.
Same-day inspection
Same-day inspection — booked in the morning, completed in the afternoon, report delivered evening — is genuinely available in Melbourne, Sydney, Brisbane, Perth, Adelaide central areas. The premium is significant:
- Same-day inspection + report: $200-$400 above standard ($750-$1,100 total)
- Saturday/Sunday same-day: additional 15-25% weekend premium
Practical constraints on same-day:
- You need to confirm property access with the agent before contacting the inspector. Without a confirmed access slot, same-day is impossible
- Most same-day reports are typed in haste — they cover the ground but are less polished than 7-day reports
- The inspector is rushed, which sometimes (not always) means less thorough inspection. The major defect categories will be caught; minor items may be missed
Weekend bookings
Most metro AU inspectors will work Saturdays for a 15-25% premium. Saturday is actually the MOST common inspection day for pre-purchase inspections — it fits the post-auction timeline (Saturday auction Saturday → Saturday inspection the following Saturday) and works for buyers with weekday jobs.
Sunday work is less common — many inspectors specifically block Sundays. Those who do work Sundays charge time-and- a-half (around 50% premium).

By scenario — booking strategy
Cooling-off (3-5 business days)
Book within 24 hours of signing. Pay the expedite premium. See booking during cooling-off state-by-state for the operational guide.
Pre-auction (5-7 days before)
Book 7-10 days before the auction date. Pre-auction inspectors have higher demand on auction-week Saturdays. See pre-auction building inspection guide for the full strategy.
Conditional contract (subject-to-inspection clause)
Standard booking window. The contract typically specifies a 7-14 day inspection clause. Use standard pricing (no expedite premium needed).
New-build PCI (Practical Completion Inspection)
Book 7-10 days before scheduled PCI date. New-build inspectors are a different specialty — use a firm that explicitly markets new-build PCI services.
Where Report Decoded fits
Report Decoded analyses your inspection report PDF once it's delivered. The analysis takes 2 minutes from upload. Combined timeline:
- Inspector delivers report → upload to Report Decoded immediately
- 2 minutes later → plain-English defect summary + cost-banded estimates + drafted negotiation letter
- Total inspection-to-decision-ready window: report turnaround + 2 minutes
For buyers in cooling-off, that 2-minute analysis compresses the “read the 60-page PDF” step from 2-3 hours to instant. Critical when the cooling-off window is tight.
