Under the stage 4 restrictions enforced throughout metropolitan Melbourne, residents can exercise for one hour each day, within five kilometres of their home.
Unfortunately, some Melburnians have little or no access to parkland within their permitted 5km radius, meaning they are likely to miss out on these benefits.
Space to breathe
For each mesh block zoned as residential, we tallied up the total area zoned as parkland within a 5-kilometre radius. The results are shown in the interactive map below, in which darker greens indicate a larger area of available parkland (very light green: 0-4.5 sq km; light green: 4.5-9.2 sq km; mid-green: 9.2-13.2 sq km; dark green: 13.2-19 sq km; very dark green: more than 19 sq km).
Of the 42,199 residential mesh blocks currently under stage 4 restrictions, 3,496 have between 0 and 4.5 square kilometres of parkland within 5km. This equates to about 135,000 homes or 340,000 people with little or no access to parks within their permitted area for exercising.
On average, residents in Cardinia, Mornington Peninsula and Melton have the least parkland within a 5km radius, whereas those in Knox, Yarra and Banuyle have the most.
Haves and have-nots
Our findings confirm that some Melburnians are more fortunate than others in their ability to access urban green space during stage 4 lockdown.
For those less fortunate, the state government should consider replacing the blanket 5km rule with a special provision that allows people to travel outside this radius if they would otherwise be unable to access a park.
Bespoke rules could also help others, such as residents with a disability or older Melburnians who use a mobility aid. While many members of these groups might have plentiful parks within their 5km radius, they may have problems accessing them. Issues can include uneven pavements, kerbs without ramps, or steeply sloped paths.
The state government could help these people by auditing public spaces to establish where structural barriers exist, and then work to remedy them. Alternatively, once again, the blanket 5km rule could be amended with a special provision that allows older Melburnians, or those with a disability, to travel outside their 5km radius to get to the most suitable nearby park.
