I ranked every Tasmanian suburb and postcode using the 2021 Census
I've been building a postcodes/demographics site as a side project, and I put together a breakdown of Tasmania using the 2021 Census + the national address file. Some bits I found interesting:

• Launceston (7250) - 51,133
• Devonport (7310) - 28,635
• Howrah (7018) - 23,450
Highest household income (median/week)
• Relbia (7258) - $2,358
