What Form 23 actually is
In Victoria, every registered swimming pool and spa must have its safety barrier inspected and certified on a rolling four-year cycle. The certificate — a certificate of barrier compliance, lodged on Form 23 — is issued by a registered building surveyor or building inspector after an on-site check against the barrier standard that applied when your pool was built.
Once issued, the certificate must be lodged with your local council within 30 days — it effectively expires as a lodgeable document after that, and you'd need a fresh inspection. Council charges a small lodgement fee (around $22, indexed annually).
The four-year cycle
When you registered your pool, council confirmed which barrier standard applies and the date your first certificate was due. Each lodged certificate resets the clock: your next one is due four years on. Council writes to remind you — but the obligation is yours whether or not the letter arrives.
- Register pool or spa with council (one-off)
- Book a registered inspector before your due date
- Fix anything that fails, get re-checked
- Lodge the Form 23 with council within 30 days of issue
- Diarise the next due date — four years out
What it costs
Inspection fees in Victoria typically run $200–$450 for a standard backyard pool — higher than QLD or NSW, partly because the inspection is against the standard from your pool's construction era, which takes more assessment work. Add the council lodgement fee. If the barrier fails, you'll pay for fixes and possibly a re-inspection; many inspectors bundle one re-check.
Councils can issue on-the-spot fines for failing to lodge a certificate by the due date, with larger penalties available through the courts — on top of which you're still up for the inspection. If you're overdue, book now; councils are generally more interested in compliance than punishment when you're visibly fixing it.
Which standard applies to your pool
Victoria assesses barriers against the rules in force when the pool was built: broadly, pools from before April 1991, from 1991 to April 2010, and from May 2010 onward each have their own applicable standard. Your council's registration confirmation tells you which applies. This matters — an older pool isn't automatically required to meet the newest standard, a point inspectors handle routinely.
