Cottesloe's well-heeled are putting in Perth's longest hours at work.
New figures from the 2011 Census show almost a quarter of all working people in Cottesloe spent at least 49 hours a week doing their job.
It is the highest proportion across Perth of people carrying out what is termed extreme hours.
A third of Cottesloe's male workers put in more than 49 hours a week working, with more than half of the beachside suburb's mining workers spending long periods at work.
It may be one of the reasons Cottesloe has a median family income of $2799 a week, more than $1000 better than the State median.
One of those putting in the hours is Cottesloe company director Gary Brockman, who runs a plastics manufacturing business in Henderson.
Mr Brockman, who spoke to _The West Australian _after an early morning swim at North Cottesloe beach, said it was logical that Cottesloe residents worked long hours.
"They are affluent and obviously they have got there by dint of hard work," Mr Brockman said.
"It's not all work and no play. We work hard and we play hard."
The golden triangle of western suburbs is home to others who spend long hours at work.
Almost 23 per cent of Nedlands' workers put in more than 49 hours a week, 21.7 per cent of Peppermint Grove's workers, 20.3 per cent of those in Claremont and 19.8 per cent of workers in Subiaco.
Central Perth (22 per cent) and Cambridge (20.3 per cent) were other inner-city councils with big numbers of people working long hours.
In Serpentine-Jarrahdale, almost 21 per cent of people are at work for at least 49 hours a week, partly because of many mine, transport, agriculture and construction workers.
It's a different story in the Canning council area where 14.1 per cent of the workforce -the lowest proportion in Perth - worked more than 49 hours weekly.
Although Canning has many mining workers, who have high rates of long hours, the council also has many retail, hospitality, education and health workers who tend towards shorter hours.
Across the State, almost 48 per cent of the population worked at least 40 hours a week, a half percentage point fall on the 2006 Census.
Last year's Census shows most Australians don't work a 38-hour week. Just 18 per cent said they worked a 35 to 39-hour week.'It's not all work and no play. We work hard and we play hard.'"Cottesloe resident *Gary Brockman *
