The picture on the right actually does show the water is higher up the base
than the picture on the left....

Fort Denison - that's where there's a tide gauge.....

OP is clearly false - I've seen the sea level rise in Sydney harbour in my
lifetime, and then the tide goes out again.

Photos cannot determine this but without "seeing for yourself" it's
hard to comprehend things.
Tide gauges, which continuously measure water height over time relative to land,
are a reliable way to determine the extent of long-term sea level rise in an
area, according to scientists.
This method has been used to measure sea level at Fort Denison, located in
Sydney Harbor, since the late 1800s.
That long-term tide gauge “has recorded a gradual ... but fairly consistent
rise in sea level of 0.1mm/yr or 3 inches/century,” according to Gary Griggs,
a professor of earth sciences at UC Santa Cruz. “That rate appears to have
increased over the past decade.”
This rate – while not insignificant – is lower than the global average,
scientists said. That’s because tide gauges measure sea level relative to the
land, which is also rising in Australia.
Found that blurb on USA Today if you can believe it.
