Sea levels on the Perth coastline are rising at three times the global average, the latest State of Australian Cities report shows.
In a statistic that federal Infrastructure Minister Anthony Albanese described as "disturbing" and "extraordinary", readings since 1993 have indicated sea levels are rising by between nine and 10 millimetres per year.
The global average is around three millimetres per year.
With temperatures rising and rainfall falling, environmental changes are having little effect on the numbers of people moving to Perth, with the city population growing by 2.6 per cent since 2001 - making it the fastest growing capital in the country.
That expanding population was having little impact on transport habits, with almost 80 per cent of people still travelling to work by car and only 12 per cent by public transport.
Perth also has the lowest proportion of people walking to work of Australia's capitals, with only 2.6 per cent of people leaving their car or bike at home.
In 2011, Perth also experienced 50 days over 35 degrees, which was the peak of a three-year spike in temperatures.
Perth mayor Lisa Scaffidi said the report highlighted major issues the city would deal with in the next decade.
"The worsening traffic congestion we are experiencing should act as a wake-up call to us all," Ms Scaffidi said.
"And of particular concern in the State of Australian Cities report is the observation that Perth has experienced a reduction in average annual rainfall between 1952 and 2011, so obviously we all need to be smarter in terms of building design and water efficiency."
