Some alternatives here, although intended for remote sites. Most everyday urban areas have a maximum building height limit - typically around a maximum of 8m. One other supplier for an open landscape actually preferred a 50’ (approx 16m tower height to get clean air and minimise terrain drag/turbulence. There are also vertical axis design wind turbines which may better suit an urban landscape, subject to council approval and having reliable clean air flow. As @gordon suggests, extremely unlikely.
The big consideration is wind energy increases or decreases with the cube of the wind speed.
IE A typical axial flow propeller like wind turbine will provided rated power at a wind speed of around 10m/s or approx 36kph. If the wind speed drops by half to 18kph (5m/s, 10knots), still a decent breeze, the turbine power will decrease by a factor of 8, (2cubed). Hence a 2kW rated turbine will only produce 250W if the wind speed simply halves.
Urban Australia is also not very windy most of the time. The BOM can help.
