Sadly, it appears that WA Govt. guidelines for sea level rise are well out of date:
Ref 1: www.wa.gov.au/government/publications/wa-coastal-zone-strategy
Ref 2 www.wa.gov.au/system/files/2021-07/CST-WA_Coastal_Zone_Strategy.pdf
Ref 3 www.wa.gov.au/system/files/2021-07/CST-WA_Coastal_Zone_Strategy_summary_brochure_web.pdf
Ref 4 www.transport.wa.gov.au/mediaFiles/marine/MAC_R_SeaLevelChangeInWesternAustraliaReport.pdf
Extract from Ref 2:
"The WA Government has adopted 0.9 metres for sea level rise over a 100-year planning timeframe for future coastal development"
It appears that the out-dated source for this information is Ref 4:
Ref 4 (02/02/2010 DoT) extract:
It is recommended that this advice be reviewed when the IPCC Working Group I contribution to the Fifth Assessment Report is finalised (currently scheduled for 2013).
The IPCC has released Assessment Reports 5 and 6 since these guidelines found their way into government policy.
As stated in the WA Gov. guidelines - minimization of risk to public funds is of primary concern when approving new developments.
In the case of Pinnaroo Point, a major "beneficiary" to proposed protection works is the PRIVATE Hillary Beach Club (under construction).
The City of Joondalup meeting of council 23/05/2023 has several items of critical interest to WWA especially for local sailors.

Urgent: Say No to rock groynes at Pinnaroo Point
WWA Committee have formed the opinion that...
IT IS NOT IN THE INTERESTS OF BOARD SAILING to allow beach groynes to be constructed at Pinnaroo Point at this time.
Please help us by submitting your strong opposition in this short survey, from the City of Joondalup:
www.research.net/r/XHFPSKJ (before the end of July)
There are just 3 questions to fill in and it takes 2 minutes!
* The City of Joondalup is rushing at an opportunity to obtain State and Federal funds for adaptation using 17 new rock groynes between Hillarys and Ocean Reef marinas.
* Hillarys beach erosion can continue to be managed using sand "nourishment" (bypassing sand around Hillarys Boat Harbour) for decades.
* The City have not properly engaged with coastal user groups as required in State Planning Policy 2.6.
* The City have not engaged with relevant academics and experts.
FURTHER READING
Experts in related disciplines, like Dusan Mills (Ex. WWA President) and scientific literature generally supports the current WWA Committee position:
* WWA - Get on-board - say no to rock groynes

Fig 9-4 in the Public Facing CHRMAP and Figure 8.13 of the Technical Report shows:
i) The start of groyne-7 lines up with the northern reserve boundary at Pinnaroo Point.
ii) due to the angle of the path and groyne, it would enter the water near to where windsurfers and foilers regularly launch, opposite BENJ123 path.
iii) groyne-7 is earmarked for 2025.

for what it's worth here's the text I used in my response if it helps others save time in their response to the draft coastal management plan survey. Deadline is end of the month.
As WACruizer says it's very dissapointing theCity doesn't intend to release:
* M.P. Rogers CHRMAP Technical report.
* M.P. Rogers Costs / Benefits Analysis - public / private benefit report.
These are two essential refences. Not sure why the City wouldn't provide these ?
feel free to use some of this if it saves some time ->
"References to Pinnaroo Point being identified as an area susceptible to coastal erosion and having experienced substantial erosion to date are vague and not available - "Seashore Engineering Pty Ltd 2019", "Department of Climate Change 2009". Pinnaroo Point also has substantial sand deposition during summer - for balance Figure 1-1 should show the same locations in summer - that would highlight the stupidity of putting those fences on the beach in the 1st place.
No clear science explaining estimated future coastal erosion, and the rate at which the coastal erosion is predicted to occur. The City engaged "MP Rogers and Associates" a small local consultancy to predict future erosion and references a 2016 report, that isn't available, nor is it clear whether it was peer reviewed. It would have been interesting to see a short term prediction in 2016 to 2024 (8 yrs) to see how it aligns with current reality. Instead we have to take the 2065 and 2115 predictions as accurate - surely there are very large error margins on these "Coastal Hazard lines".
Where is the cost benefit analysis report (reference 11 links to "MP Rogers and Associates 2022"). There is no transparency to what social and environmental costs were used.
Community coastal values survey of only 1,318 respondents over one month in 2018 is not sufficient, this is but a tiny fraction of the beach using community. Even this very limited survey indicated to the city that the community is opposed to "hard engineered protection structures".
