You 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.
