Update 12 Feb 2021 Added Bonus Pics of Trigg Island courtesy of Chris Holyday author ‘Between Beach and Bush’ book.
Trigg suburb and the
small island off the coast in this area were named after Henry Trigg,
Superintendent of Public Works for the Swan River Colony in 1842.
In 1919 there were
only 3 buildings in the locality, and holiday and fishing shacks begin to
appear in the 1920s.
Trigg
eventually started to be formally developed in the late 1940s, when 1,888 lots
were subdivided and sold. Many of the streets in the area were named after
former residents and pioneers, as well as local personalities. Source City of Stirling.
Trigg Point
In the summertime the quality of Trigg Point waves is dependent on the south westerly sea breezes moving sand from Scarborough and beyond to the reef area at TP. At the end of summer, northerly winds move the sand back to the Scarborough region.
The following photo taken in 1949 shows exposed coastal reef and undeveloped land at Trigg Point. Judging by the lack of beach sand it was probably taken during the winter season.
The waves at Trigg Point attract the biggest crowd in the metro area, but has the wave shape and length of ride changed over the years?
Man-made changes to natural beach formations at Trigg Beach for beach safety and erosion reasons, may have impacted on the annual sand movement and wave quality at Trigg Point.
Trigg’s old-timers talk of sections of the reef near the
‘Blue Hole’ and in front of the Trigg SLSC being blown up in the 80s.
Man-made changes at neighbouring beaches south of Trigg, may also be impacting on the annual sand movement to TP.
Scarborough beach
Tom Blaxell (WA Surf Industry pioneer and Scarborough surfer). “I remember the setup on the massive sand beach at Scarborough in the 60s, before the Authorities put in the artificial vegetated dunes, which were installed to control the seasonal sand drift, which used to clog up the carpark, and I think to help against beach erosion.
As a consequence, it seems that the underlying reefs, like Three Penny Reef, and even Trigg Blue Hole don’t get exposed nearly as much as they used to, in winter in the old days. The Rocky bluff that stands at Trigg Point used to separate from the beach in winter, hence it used to be called Trigg Island (the SLSC Club is still called that), but which has now become known as Trigg Point.
I remember around 1980 the City of
Stirling working out that the beach at Trigg Point was growing by about half a
metre per year. As a result, the point has become less of a point than it used
to be.
The following image shows the vast white sand beach prior to the implementation of artificial vegetated dunes circa 1983. That’s the Brighton drain outlet in the foreground (right). Sometimes that turned into a river like at Smiths Beach Yallingup”.

Tom
Blaxell – “I
think we all have memories of the best waves, usually in the past.
It’s
hard to be precise in these things, and certainly seasonal sand movements and
aggregations are a rough science.
But
certainly, the City of Stirling thrust was to build up and stabilise the sand
aggregation, to reduce erosion & coastal damage in winter, when a lot of it
got washed away.
I
used to be on their Coastal advisory committee, chipping in viewpoints from a
surfer’s angle, but I’ve got to say their strategy has worked, from their
angle.
The beach line does seem to be more stable than it was in the old days. As a result, I believe that the coastline sand formation is generally straighter, with less irregularities & peaks. So yes, it could be the case that there is a lowering of quality for surfing these days, compared to the original natural formation”.
It’s debatable whether changes to the annual sand movement and wave quality at Trigg Point is due to man’s intervention of the natural beach process or Mother Nature (who is a very fickle lady) changing weather patterns.
It would be interesting if there is scientific evidence of any changes in wave quality at TP.
