from the Adelaide Hills into the CBD along Greenhill Road. Buses typically run on 30-minute intervals during weekdays and one-hour intervals at other times. Unfortunately, due to the heavy emphasis on car transport in the area, the bus routes are limited and under-developed, particularly compared to the efficient public transit links to the rest of metropolitan Adelaide. Residents According to the 2021 Census the population of the Hazelwood Park census area was 1,953 people. Approximately 51.0% of the population were female, 68.2% are Australian born, and the median age is 43. Hazelwood Park has an educated population with over 40% of the population holding a degree or diploma. This level of education attainment is reflected in the suburb's employment patterns: the most popular industries for employment were Education, Cafes and Restaurants, Health and Community Services, finance, insurance, and business services. The median weekly household income is $2,300 or more per week, compared with $1,455 in Adelaide overall. Hazelwood Park has a higher than average stable family population with a large segment of both children and their mature aged parents. Most residences are family occupied but the number of older empty-nesters (whose children have left home) is growing. Retired population is relatively low, but continuing to grow. 76.3% of dwellings were detached houses but this figure is falling in favour of attached dwellings. Subdivisions are also becoming very much of a common sight in recent years. The number of development approvals has been falling since the 2001–02 financial year. Attractions The biggest attraction in the suburb is the park and accompanying Burnside Swimming Centre. There is a lap pool, plus a 25-metre kids pool and a wading pool. There is also a sauna and steamroom, plus two playgrounds and a kiosk. This location is only open through summertime because it is an outdoor pool and is very popular on hot days in Adelaide (greater than 300C) when it is open late. First creek continues its journey from the hills through the park, the water flowing from Waterfall Gully and into Tusmore. The creek cuts through the middle of the park and is dammed at one point to create a pond. This is a popular place for children to feed the ducks and families to sit by. There is one playground in the north-east of the park and there are several sets of tables and a few barbecues dotted throughout the park.
